FontForge patched font render issue on most terminals (not Gvim)

Hi,
I'm using the powerline plugin for vim with it's glyph-mode which requires a patched font using the fontpatcher (FontForge). The patched font works fine with Gvim and some terminal emulators, but gives corruption/artifacts on others. I'm not sure whether this is an issue with the patched fonts, a common bug across the terminals tested or maybe those terminals it work with just have better rendering.
The issue is added to powerline issue tracker, but I'm not sure if it's actually caused by the FontForge-script used to patch the fonts or something else.
In other words; I don't know where to start since it's so common with terminals but not in Gvim. If the fontpatcher is broken or not, since it's working perfectly fine in Konsole (i.e. identical as in Gvim).
See screenshots for examples on font corruption: (vim taken in terminator)
Vim at pt.8
Vim at pt. 14
Gvim at pt.8
Gvim at pt.14
Working:
Mintty
Konsole
Not working:
Terminator
Gnome-terminal
Xfce4-terminal
LXTerminal
PuTTY (can't even find the appropriate font..)
I couldn't get urxvt to use the right encoding or whatever for the glyphs to work.

Staff? Text rendering incompatibility Safari 7.06 and Muse 2014.1.1.6 Websafe fonts render issue

Text rendering incompatibility
Safari 7.06 and Muse 2014.1.1.6
Websafe fonts render poorly when on top of a
‘Browser Fill’ has ‘Image added’ and ‘scrolling’ check box left unchecked’
or when
Any ‘composition is set below the text and composition is set to ‘pin’
Comparison Web safe fonts render
Chrome = all good
Firefox = all good
Safari running on ‘non-retina’ displays = bad
As mentioned these are websafe font / also occurs with self/hosted fonts
unfortunately client is viewing on Ipad that is non retina and uses Safari.
Any work around?
Thanks
Milton

Hi Zak
Thank you for your prompt response.
I have been reviewing this issue on a number of screens an Browsers – I realise the huge hassle of compatibility comments.
Below links and further explanation and screen shots
Thanks again
Milton
Web safe fonts (e.g. helvetica / arial) render poorly when:
Any ‘composition’ is set below the text and the 'composition' is set to ‘pin’
See first scroll page at www.edehorton.com
The top slideshow is 'pinned' and it is this action that creates the issue for text on the whole page.
It also occurs when text is on top of a ‘Browser Fill’ that has an ‘Image added’ and ‘scrolling’ check box left unchecked’
See first scroll page a www.edehorton.com/judaica.html
creates the issue for text on the whole page.
I can remedy these situations by ‘unpinning' the 'compostion’ or placing the ‘pinned' 'composition' above the text
or in the second instance by turning the ‘scrolling’ radio check button in ‘Browser fill’ on.
Screen snap shots below
Comparison 'Web safe font - Helvetica' plus 'Webfont' render
Chrome = all good / Firefox = all good /Safari running on ‘retina’ displays = all good Safari 5.06 on' non-retina' = all good
Safari 7.06 running on ‘non-retina’ displays = bad

Font render issue after upgrading to iOS 4.2.1.

Hi,
I happen to have a friends iPhone, trying to restore it with original firmware 4.2.1, but it keeps a font issue where it has trouble getting it right.
http://www.stepserver.nl/~step/3gs1.PNG
http://www.stepserver.nl/~step/3gs2.PNG
I tried to recover the iPhone in any way, tried different languages. Inverted the screencolors all to no avail. Does anyone have any idea what I can do to correct this issue? Or is this an overheating problem (GPU related), however the icons and background and rest of the iPhone is alright (except all the fonts..)

I have the same issue after iOS 4.2.1 update. I am using iPhone 3GS officially unlocked by Apple. I tried using different SIM cards and both carriers show same problem when using phone in 3G mode. Phone falls back to EDGE mode showing 'E' from '3G' at start. I have reset the phone and rebooted several times and moved to different cell areas in the city just to verify the problem.
I had no such issues earlier. I also have Nokia E71 which shows full signal and has no such issues.
I have posted the bug on apple iphone feedback page. I hope they Apple will fix the problem and test the release properly on all models before releasing to public.

Gpu font render issue air 2.6

ok so I have an air for ios 2.6 app where 10 ladybirds walk onto the screen and have words attached to them. They walk on using a tween. When they have no text on them and the app is set to GPU mode its a really smooth animation. But when the text is applied to them its unworkable. I assume this is because the text is a vector.
I need the text fields to be dynamic and ideally i want them to be part of the tween.
What do i need to do here to improve this performance?

i think i get you
Yes my words are in a text file and load into a variable then 10 are chosen at random at sent to the dynamic text filed then it's a timeline tween gotoAndPlay(2)
so what I need to do is between setting the word and setting the gotoAndPlay(2) I put
my_movieClip.cacheAsBitmap=true
right?

Mac OS10.9 Quark 9.5.4 - font leading issues

Mac OS10.9 Quark 9.5.4
Recently upgraded OS and Quark and my documents that use the font Avenir are not displaying correctly. Fonts leading has expanded so anywhere Avenir is used, the leading changes the layout and most text boxes are overset.
- leading is set to Auto
- do not use a font manager, I use FontBook- checked usage and font is not missing
- deleted Avenir, emptied font cache, restarted and issue still exists- made a new user, packaged a file, opened in new user and issue still exists
- not just one file, issue exists in every file I made that uses Avenir in my archive- had my colleague open the same archived files on their computers and files were correct
- had colleague send me Avenir font, deleted out of my library, reloaded font and issue still exists
- deleted font out of my library and just used Avenir system font, issue still exists- deleted Quark and re-uploaded, issue still exists
- re-uploaded OS, issue still exists- did a thumbnail transfer of items from old doc to a new doc, issue still exists
- have spent over 6 hours on the phone with Quark support and have numerous messages back and forth in a job ticket, no resolution
I would not normally use Quark, but a client reuqests it. I suspect I might have a corrupted system font but I am unsure. 3 weeks behind schedule on my project and am desperate for help. Any ideas?

I just found out my E3000 was no longer compatible with making a Guest Access password. Spent a ton of time online chatting with a Linksys/Cisco rep who told me it was not longer compatible with the newer operating systems...BUT THIS IS A LIE! My E3000 works great with Yosemite. A couple of things you need to know. 1. You can no longer use the Cisco Connect CD to set up a Guest PW. It has been replaced by a handy App, that you can download from the App store: http://www.linksys.com/us/support-article?articleNum=156285 2. You can change the settings on your Wifi router directly from this app. No need to go into the 192.168.1.1 site and configure it but if you want to, you still can do this. On the website, there is no way to configure the GUEST settings unfortunately.... 3. You can configure a Guess Access code and set the number of computers allowed to use it at one time on the App. After you set the code, it will bring you off line then online again. Make sure you log in to your WIFI network under both Guest and your WIFI network to see if works. For some reason, it took some time for my iPhone to bring me to the Guest sign-in page, but I eventually switched the ON/Off button on the Guest Password setup and it worked. All guests should be redirected to a CISCO SIGN-IN page where they can log in with the guest Password. 4. I can't believe the customer reps didn't tell me immediately about this app! I gave it 1 star as it wasn't working very well until I reset everything and started over. Maybe that was just my incompetence.... Good luck! My 5 yr old dual band router is still working very well! No need to get a new one to be compatible with Yosemite!

Font Rendering Issues-Help Required Please

In the past week, any Google search on Firefox or Chrome (but not Opera) gives me results where the fonts look gappy. Sometimes there are additional dots above the letters. I uninstalled and reinstalled Firefox from scratch in case an add-on was at fault but even with a clean install I am still seeing the issue. I checked my font settings and do not have any minimum font size set. I have allow pages to choose their own font ticked.
I've uploaded an image where I can see some correctly rendered text and some gappy looking text (not from a Google search but a Mozilla query). It also happens when commenting online sometimes, during typing it will be gappy but it will show properly once submitted. Any ideas for a fix would be warmly welcomed and I can give more examples if that would help. Although it's not Firefox related, I did restore all defaults in Chrome and it didn't fix the issue there either.
I uninstalled the most recent Windows Update since the problem is recent but it didn't change anything. I'm not sure if browsers would even look to my computers fonts.

hi Auds77, this is probably caused by microsoft update kb3013455 which can cause font rendering issues on vista:
<blockquote>After you install security update 3013455, you may notice some text quality degradation in certain scenarios. The problem only occurs on systems that are running Windows Vista SP2 or Windows Server 2003 SP2. Microsoft is researching this problem and will post more information in this article when the information becomes available. </blockquote>
<sup>reference: https://support.microsoft.com/kb/3013455</sup>
one option may be to [http://windows.microsoft.com/en-us/windows/remove-update#1TC=windows-vista roll-back this particular update] for now until there is a fix by microsoft or you could also look if there is a [[Upgrade your graphics drivers to use hardware acceleration and WebGL|graphics driver update]] available on the website of the vendor (intel/amd/nvidia) which might also resolve this problem in some cases.

Font rendering issue & multimedia keys not working

Hi, yesterday i switched to KDEmod 4.1 and I have two major problems...
One is font rendering issue... I did not change anything in my font-related packages (cairo, freetype, fontconfig, libxft) and i have to add that this setup worked perfectly in KDEmod 3.5.9, but now it looks like this:
This bug occurs only in qt apps and mostly in kmenu... i.e firefox renders my fonts flawlessly...
Second problem are multimedia keys on my keyboard...
They worked in KDE 3.5.9, but now I cannot set them up properly... Sometimes they work, sometimes they don't...
KDE recognizes the pressed key, but when I assign specific action and press the key, just nothing happens...

You might be able to solve your font issue by going to System Settings -> Appearance -> Fonts. I enable ant-aliasing. I also clicked on configure and select "Use sub-pixel rendering" to RGB and the hinting style to Full. I also use the Force fonts DPI to 96 DPI. This makes the fonts pleasing to my eyes.
This is how I got my multimedia keys to work in KDE4.1:
Go to System Settings -> Regional and Language and make sure to set the County or region to your location.
khotkeys needs to be running. I added it to the autostarted progam list. System Settings -> Advanced tab -> Autostart
When I got the multimedia keys working, I was really tring to get the keyboard shortcuts to work. In addition to the above steps, I also deleted
~/.kde4/share/config/kglobalshortcutsrc. I do not know if deleting this file is needed to get the multimedia keys working, but it was to get the keyboard shortcuts woring.
Restart X
Go to System Settings -> Keyboard and Mouse -> Keyboard Shortcuts
I set the volume control in the KMix component section.
To get the keyboard shortcuts to work, go to the menu editor and select the program you want to create a shortcuts for. Click on the advanced tab and create the shortcut in the shortcut field. Save.
Then go to System Settings -> Keyboard and Mouse -> Keyboard Shortcuts. Change the component to KHotkeys. Select the Program and then select the default shortcut that you just created. (This works for the multimedia keys aswell).
Hope this helps,

FAQ: How do I clear out my font cache to fix font style and duplicate font style issues?

We have a Script availabe for CS6 beta users who are experiencing particular font related issues.
This script will help by clearing the font cache and will test for corrupted fonts.
This will solve some of the type issues with duplicate font names and some of the other font errors.
This script is to help to find corrupted fonts. The script itself doesn’t solve the problem.
This script doesn’t solve duplicate font name, but clears out your font cach . It it will solve some duplicate font style name issues such as the one in the link below.
http://forums.adobe.com/message/4306828#4306828
There is a pdf file explaining how to use the script and what it will do.
See attached files.

Monica, I know the Normal Character Style in Illustrator must be defined. But my question is about the Normal Paragraph Style, not the Normal Character Style. As Larry just said, in most of my documents, and in my New Document Profiles, these fields in the Normal Paragraph Style are blank (undefined), so I know this is possible. In a few older documents I'm converting, the Normal Paragraph Style has a defunct font, and even though my Normal Character Style is correctly defined with the current font, it's creating some weird behavior.
Larry, it doesn't appear to be the document itself, it just appears to be not knowing what the right keystroke combo is to clear it. Just make a new file from a Document Profile where the Normal Paragraph Style does not define one of those font fields, define a font and/or font size, save, then reopen the paragraph style settings and try to clear any field that has been set. I can't clear it, I can only change the font.

PS Smart Object Import Render issues from AI

I have scoured these forums for a while to find anything regarding these circumstances. I apologize if this has been mentioned before but I'm trying to find some way to mitigate this issue.
When importing a vector smart object into Photoshop from Illsutrator I end up with text rendering issues. The fonts render as if they were assigned the sharp AA setting, despite having the crisp AA setting on the AI source.
The pixel previewed AI opened vector smart object looks clean and crisp.
Any ideas on how to fix the text rendering issues?

MS Courier New font render error in new QT5 apps

Hi all, just updated some KDE apps to new QT5 versions and got weird issue with monospace apps. I've MS Courier New as monospace font and in new qt5 apps letters have wrong height while upper part is rendered correctly. It is like someone cut off bottom of the symbol. Is there any workaround to make qt5 render Courier New properly?

my test letters are still in the same alphabet
To generate non-Latin text in a modern OS you can't just change the font, you need to change the keyboard layout. Go to system prefs/international/input menu and check the box for Hebrew or whatever you want, plus the box for "show input menu in finder." Then select Hebrew in the "flag" menu at the top right of the Finder and type.
You need to make sure you use Unicode fonts. Also MS Word does not yet support correct Hebrew, so use another app. For that script, Mellel is the best. See the applications section of this note:

Patched Fonts: Cleartype vs Ubuntu

Hello everyone.
I have a small "aesthetic" issue with both of these patched fonts. Cleartype looks really dodgy and ubuntu fonts look huge. What I'm actually looking for is for exactly the same emulation of msfonts windows7 cleartype on my machine or ubuntu fonts but really smaller than the one's I'm getting.
Any suggestions?

I'm using Infinality with (I think) the default settings. This did seem to help things but code in the Arch wiki now looks awful.
I'm not quite sure about the interaction between the files in /etc/fonts/conf.d and the Infinality config. As I understand it, lower numbered files in the former have priority which means that everything less than 52- trumpts Infinality's config?
10-cfr-antialias.conf@ 20-unhint-small-vera.conf@ 51-local.conf@ 69-unifont.conf@
10-cfr-bcihint.conf@ 29-replace-bitmap-fonts.conf@ 52-infinality.conf@ 70-no-bitmaps.conf@
10-cfr-lcdfilter-default.conf@ 30-metric-aliases.conf@ 57-dejavu-sans-mono.conf@ 80-delicious.conf@
10-sub-pixel-rgb.conf@ 30-urw-aliases.conf@ 57-dejavu-sans.conf@ 90-synthetic.conf@
20-fix-globaladvance.conf@ 40-nonlatin.conf@ 57-dejavu-serif.conf@ README
20-unhint-small-dejavu-sans-mono.conf@ 45-latin.conf@ 60-latin.conf@
20-unhint-small-dejavu-sans.conf@ 49-sansserif.conf@ 65-fonts-persian.conf@
20-unhint-small-dejavu-serif.conf@ 50-user.conf@ 65-nonlatin.conf@
Also, I installed three additional custom config files here in my attempt to follow the Arch wiki but I'm not sure whether I should still have them there with Infinality in the mix. These are all numbered 10- and essentially: enable anti-aliasing; full hinting (I have a note saying this is recommended with the BCI); set lcdfilter to lcddefault. But then I'm not sure what the Infinality settings are doing in this case... Should these more specific tweaks suggested by the wiki be disabled if using Infinality? Or at least the tweaks for anti-aliasing and full hinting? Are these overriding any fonts specific settings given in the higher numbered config files? Or do those take precedence over default settings regardless of place in the configuration file hierarchy?

Best way is to restore your backup from before the problem, rebuild it and update it again

Font smoothing issues

Hi all. I noticed some others were complaining about font smoothing not seeming to work in Carbon applications (e.g. Camino, Firefox, MS Word and even iTunes). It seems the subpixel font-aliasing system preference (e.g. light) is ignored and, instead, the ugly CRT font smoothing is used.
I am puzzled this has not received a lot of attention, since it immediately bothered me when I received my Macbook Pro today.
Is everyone experiencing this font smoothing problem? I used the Migration Assistant to copy all files from my previous (Tiger-installed) Powerbook. Does anyone not having used the Migration Assistant also suffer from the font smoothing issue?
For more info, see http://discussions.apple.com/thread.jspa?messageID=1829478&#1829478
Macbook Pro Mac OS X (10.4.6)

TinkerTool didn't make any difference for me. I played around with it and found that there was no improvements using it or disabling font smoothing.
I have watched DVD's on this LCD being played with my MacBook. I have seen 2MB+ full screen digital pictures. Both the DVD and digital pics look absolutely amazing on it.
It's only the fonts that appear blurry or in some areas they appear to have a shadown to the right. This happens with any text that appears in every app.
Keep in mind too, Windows Vista looks perfect on this display, but my prized MacBook looks really sub-par.
I'm not quite following you on changing the display preferences to change to pixel size to that of the MacBook...

Font smoothing issues with Samsun 23 inch LCD

I am having a font smoothing issue with my MacBook and my Samsung LN-S2352W 23 inch LCD (http://www.samsung.com/Products/TV/LCDTV/LNS2352WXXAA.asp). I am using the mini-DVI to VGA adapter and the plugging that into the VGA port of my LCD. It doesn't matter which app I run, but as long as it has fonts, they come out blurry, hazy, colors bleed, etc.
I have played with the font smoothing settings and that has not helped at all. I have heard of TinkerTool and will try it to see if it makes any difference, but am not expecting much.
I also have a PC running Windows Vista and I connected it to the VGA port of my LCD. Wow...the difference in picture quality was astounding. I'm ******. I want my MacBook to look that sweet on my LCD.
Anyone have any thoughts? Can this be fixed?

Mac OSX: Flash CS3 Font Install Issues

Hi,
I have a Mac Powerbook G4 with OS X installed and Adobe CS3.
I've installed a font. The font works in Photoshop and Illustrator
but not in Flash CS3. Why? I've put the font in the Library/Fonts

Flash. Apparently this is a problem for a number of people see
another forum here:

Hi davidd61713525,
Sorry for not getting back to you sooner.
Unfortunately, it looks like something is wrong with the file system and the installer can't see the root drive to install to. A Google search returns numerous results affecting various products and the recurring theme is that something is wrong with the disk. There are many recommendations from various sources, but nothing definitive.
Here's a similar thread over on the Apple forums:
Broken Installer Permissions | Apple Support Communities
And a similar older one:
http://forums.macrumors.com/showthread.php?t=1203509
I would try the following options:
Try using the PKG installer. This is used Mac SysAdmins to install Flash Player within their organization and uses a slightly different installer path, which may or may not work.
Some people have had success with disk and permissions repair some have not. You can try running a disk and permissions repair. After the disk and permissions repair is complete, reboot the system and try to install again using either the online installer (get.adobe.com/flashplayer) or the offline installer, posted at the bottom of the Installation problems | Flash Player | Mac page in the ‘Still having problems’ section.
If these options do not work, I'd reach out to Apple support to see if they have a suggestion. If you do find a resolution to this, please let me know. I'll be happy to share it with people that encounter the problem in the future.
