Vertical tearing due to window in the background

I noticed this today. When there's a scrolling terminal window behind Firefox, there is some tearing on the vertical edge of the window that's in the background.
I'm running KDE 4.13 (just updated today), Nvidia 337.12 from the official repositories on a GTX580.
Here's a small movie that demonstrates it: http://youtu.be/hLT5nrCog_g
Has anyone seen this or know whether there's a fix for it?

My son was playing Guild Wars 2 in the back . I wanted to delete audio but I didn't have the tools available.
Anyway, to answer your question its KDE 4.13 (just updated), latest Nvidia drivers from the official repositories on a GTX580.
The problem doesn't exist on my laptop, intel video running OpenSuse/KDE.

Dwm: some questions (e.g. bring floating window to the background)

Hi,
currently I'm diving into the world of tiling window managers (or at least I try to).
dwm looks nice and fast (with awesome I have the feeling that changing the master window takes much time/feels slow)
One thing I couldn't find out is how to bring a floating window to the background (or a tiled window to the foreground). Floating windows always stay on top so that they prevent mo from seeing every part of a tiled window.
Thanks in advance for your help

Ok, I tried the raiselower patch but it seem it's not working. I created the file raiselower.c
void
raisewindow (const char *arg) {
if (!sel)
return;
if(!(sel->isfloating || lt->isfloating))
return;
if (!arg) {
XRaiseWindow(dpy, sel->win);
} else {
if (lt->isfloating)
XLowerWindow(dpy, sel->win);
else {
XWindowChanges wc;
wc.stack_mode = Above;
wc.sibling = barwin;
XConfigureWindow(dpy, sel->win, CWSibling | CWStackMode, &wc);
and added the line
#include "raiselower.c"
to my config.h but when I makepkg I receive the following message:
In file included from config.h:39,
from dwm.c:242:
raiselower.c: In Funktion »raisewindow«:
raiselower.c:5: Fehler: Anfrage nach Element »isfloating« in etwas, was keine Struktur oder Variante ist
raiselower.c:10: Fehler: Anfrage nach Element »isfloating« in etwas, was keine Struktur oder Variante ist
I try to translate : Request after element "isfloating" in something, that isn't a structure(?) or a variable/attribute
/edit: Ok, I also tried pertag but I think it doesn't work with the latest version of dwm. I can only switch the layout of a tag once. When I switch to another tag and back again, changing the layout doesn't work anymore (on no tag).

How to run a safari window in the background at all times?

Ok, so you are probably wondering why I want to do this. Allow me to explain. The website twitch.tv is a streaming service for gamers, and there is a browser plugin specifically for the site called betterttv.
One feature of this plugin is that you will get a notification whenever someone you are following starts broadcasting, right in your notification center. But because its a browser plugin, and is specifically for this one website, it requires a safari window to be open with the website twitch.tv in order to push the notifications.
So my question is... how can I make a browser window stay open at all times and run in the background with this website open so that I get my notifications? I had the idea that I could retain the window even when I "quit" safari, because I can run a seperate instance of it in the form of Webkit Nightly which isnt affected by safari not being running.
But I am still oblivious as to how I would set up a window like this, and it has to start at login in addition to being running throughout the day. (I shut my Mac off at night.) Any amount of help would be appricated

I'm well aware of how to minimize thanks, and it *is* possible to have a Safari window open if you quit it, because you can run it as a separate instance by using WebKit Nightly...
I am just looking for the best way to set it up so that a WebKit Nightly window will open upon startup, navigate to that webpage, and hide itself. Preferably in the background. This could be done using a .command file or a startup script in automator. My question is.. What is the best direction to take?

Can i run windows in the background?

hi there
i have recently purchased a macbook pro 13" and i know that it is possible to split the hard disk to be able to install windows OS, but i was wondering if anyone knows if it is possible to leave windows running in the background and switch back to OSX?
the reason i want to try and do this is because i have a USB device for my fish tank that monitors several peramitors and uploads them to an online account so i can see what is going on in my fish tank, however it needs a local piece of software for it to be able to do this and at the minute this is only available for windows hence my question, im hoping i can get around it by spliting my mac in this way but it needs to be able to run in the background as a parralel system.
any help would be great.

Hey,
You can buy Virtual Machine apps such as VMware Fusion and Parallels Desktop for Mac and these will let you run Windows as a Virtual Machine (on top of Mac OS X). You can then run Windows programs as well as Mac ones.
If you need any more help, please ask

DLL Modal window in the background

Hi all!
I have a Borland C++ made DLL, which creates a modal window. The DLL function hasn't got any teststand specific parameters, since it is designed for general use.
My problem is the following: I have a sequence, where I put i.e. a built-in message popup (modal) before the DLL function call. In this case my modal window is in the background, and the focus is on the teststand window.
I've read the application notes dealing about this problem, but the solution written down there is via parameter passing the engine object (in my case this couldn't be done, because my DLL function is not just for teststand).
Could anyone please help me in the problem?
Thanks
Dave

Dave,
Could you add the SeqContext parameter, but ignore it if it's zero? Then non-TestStand uses could just pass in a zero and it would ignore the TestStand specific code that makes the dialog modal to the TestStand execution it was called from. Another way might be to create two versions of the function, one for TestStand that includes the SeqContext, and one for non-TestStand use, and that one statically sets the SeqContext to zero and ignores the TestStand modal functions. This method is similar to the many of the 'FunctionName' and 'FunctionNameEx' functions that allow for different uses of the same functionality (although all the examples I tried looking for where examples of obsolete (deprecated) functions).
I can't think of any other way you could do this without adding parameters.

Clicking on an application window in the background does not bring to front

I keep several applications open at the same time and organize them with Spaces. Some applications share all Spaces like Mail, Safari, Messenger.
The problem is when I have mail as the front application and then click on Safari's window, Safari doesn't come to the front. Mail still is in front.
This happens alot and with several applications.
In order to bring the app to front - I need to click on the apps icon in the dock.
Is there a patch or fix for Leopard.

Even worse, clicking on the icon in the dock isn't always helpful. Sometimes there is no way of bringing the document in front. I have to force quit the program, very annoying.
The strange thing is, I can still open documents. I see them appear when I right-click on the icon in the dock. So the program isn't realy stuck. The mac is just unable to bring it to front.
This happens a lot with InDesign and a co-worker of mine had the same problem in Exell.

An applescript to change the background color for all finder windows

I'll start off by telling you what I am trying to achieve, then show you what I've tried.
I have a macbook with several HDD's attached. what I want is for each of those hdd to have a specific finder window background color. so no matter where I am in that hdd the background color will always be the same. so for instance if I set the background color of hdd 2 to blue then as long as I see a blue background I know that I'm within hdd 2.
I've tried setting up an applescript to do this but can only get it to change the open finder window, and none of the subfolders have their backgrounds changed.
here is what I have so far:
tell application "Finder"
tell the icon view options of the front Finder window
set the background color to {52942, 54484, 31097}
end tell
end tell
so how do I get this to apply to all subfolders without opening each one and running the script.
thanks in advance for any and all help with this

According to this article:
http://docs.info.apple.com/article.html?path=AppleScript/2.1/en/as2039.html
it seems that the various options can only be set while the window is open and in icon view.
Rather than manually opening the window of every single folder on the hard drive, it should be possible to write a script to open every folder in sequence, make sure it is in icon view, change its background, then close its window. I have never been any good at the "actions within actions" procedure needed for folders within folders, so maybe someone else with the necessary knowledge and experience might be able to assist in this regard. Such a script would probably take a few minutes to complete while it ran through "every folder of every folder", but it sure would be quicker to have the process automated than to do it by hand - computers are really good at repetitive tasks (as long as the instructions are accurate, of course!).
On the other hand, you might like to try the following:
open a few windows in icon view, choose Show View Options in the View menu (I'm in System 10.4), click the radio button All Windows, click the Color radio button under Background, then choose your color. It might achieve what you are trying to do.

How do you disable OS X (when you focus on a window) from auto-focusing on windows from the same (or similar) program on another screen

Hi,
I have what is quickly becoming a major nuisance, I hope someone here knows more than me (hopefully about to change this behaviour..?).
Whenever I click on e.g. excel on one screen, the excel windows in the background on my other screen is automatically brough to the front, hiding the window I actually want to be able to see. And if I have no excel windows on that screen, it will automatically bring e.g. MS word to the front instead.
Does anyone know of a way to disable this extremely annoying behaviour? It seems silly to have to minimize every single window (yes, I have a lot open at any given time, and need to transfer data between several different programs) just to be able to look at windows from two different programs at the same time.
Cheers,
W

this is NOT how apps behave on a Windows PC. There, the different windows of any app focus independently.
Mmm, no, not really. All Windows apps run inside an application frame. Nothing for that app can exist outside the frame. Once you are in the frame of a given app, all of (example) Excel's open documents are also stuck inside the frame. Along with any palettes or other objects for that app. You can take it off full screen display like below, but each app, and everything associated with it is in its own frame.
I mention this to show that you can do the same thing on your Mac. Where you said:
I'm clicking/highlighting to the foreground (this also applies if I use alt+tab in Windows PC; you cycle through every single excel you have open,
The equivalent on the Mac is to press Command+` (same key as the tilde ~, which should be directly above the Tab key). So it's Command+Tab to switch between apps, and Command+` to rotate between open documents within an app.
So anyway, in the same manner you would arrange your Windows apps as shown above so you can see the contents of both apps, you simply arrange your Mac apps' documents the same way. Adjust the size of each open document as necessary so you can see the relevant information.
Just like if a person were going from Mac to Windows, it's "different". Folders, files and apps? All the same concept. Saving and deleting files? Pretty much the same. But if you're very used to one, the other seems odd until the need to think about "simple" steps that aren't performed quite the same way as the OS you're used to becomes habit, and it no longer seems odd anymore.

When I open a pdf file, Firefox opens a blank window, then the file opens in a Adobe Reader window. How can I stop the blank window?

Whether I am using Firefox 3.6.8 or Thunderbird 3.0.6, clicking on a pdf file opens a new window. After a few seconds the pdf file opens in a separate Adobe Reader window. When I am done with that and close it, I still have to go back and close out the blank window. Got to be a configuration issue some place. I have tried several settings under Tools/Options, but haven't found the right setting yet. Any suggestions?

Thank you very much for the reply. I followed your instructions. This fixed half of the problem. Links to pdf files that are on web pages now come up with a box that asks if I want to open or save the file, without a blank browser window in the background. That is great.
When I tested the fix with pdf file links in email, the problem still exists. I tested links in Outlook Express, Yahoo mail, and Gmail. Any time I click on a pdf link in an email, a blank Firefox window opens and then I get the small window that asks me if I want to open or save the file. Sounds like this is a configuration issue, not a technical problem. Thanks for your help.

Pop Up - how can I make the window in the backround visible?

Hi,
when I create a popup, the window in the background becomes unvisible as long as the popup is not closed. how can I make the background window become visible when the popup is open? I can hardly believe, that such a basic feature is not supported. But on the other hand, I also have some problemes with the sizing of the pop up...
Help is highly appreciated.
Kind Regards
Felix

...just found this thread. And I am not very happy about what I read. Is your system 701 or higher?

Browsers will not go into the background

Is there a bug in the Finder causing Firefox and Safari to refuse to go into the background when I click on an open window in Word or any other open application in the Finder? Even clicking on the dock icon of the application I want to bring in the forefront will not put the browser window in the background.
This problem is 100% reproducible if I am trying to complete a form on any given web site and need to access another application for information to complete the form.

Yeah, I think there is a bug in there somewhere. I have a multi-button mouse and for years and years have habitually option-clicked on the window of another app, or on Desktop, to hide open windows of space consuming apps such the browser when I'm going to do something else for awhile. Lately I've noticed Safari sometimes, but not always, will continue to display its window rather than hiding. Sometimes a simple click on where I want to be will cause the Safari window to finally disappear. Sometimes it works just fine, as it always has before. Just noticed this oddness recently--could have been introduced with the 10.4.6 update.

Need to extend the background due to people being off the background

I recently saw a video where a Photoshop guru, using CS5 extended, Due to the lack of a larger background, the photographer found himself having to photograph this 20 people group with 16 of them inside of the background and 4 of them with half of their bodies inside of the background and the other half outside.
This guru showed that with photoshop CS5 extended he could extend the background and add the 4 subjects with ease and with only 2 stroked.
I lost the link and would like to learn how he accomplished that.
What is the easiest way to add the other half of the person on the background?

The background window is always grey. That item describes a bug which (in some release) made it a different grey.

Had an avg problem (still unresolved) now firefox does not come up at all but something in the background is working once I clicked on it - windows XP

I had/have avg toubble and now firefox will not start. I uploaded a new version but made no difference. If I click on it the time symbol comes up for a few seconds and than nothing. When I restart the computer though a small window comes up alerting me not to end the programm till it scaned it. So I figure after clicking on it something must be running in the background. But no symbol comes up on the dectop or in the application manager.
Any ideas?
Regards Franz

The Background File Activity Window Is Annoying. Any tips on removing?

So, I just started using Dreamweaver CC after having been on hiatus from the program for nearly a decade. I have to say, most of the things I hated it for, and stopped using it because of, have been corrected. Kudos, Adobe, for fixing what was everyone's least favorite program in the suite.
Anywho, all that said, I am still annoyed on a very VERY regular basis by the program issuing an extremely pesky pop-up window anytime I attempt to Put files to my Remote or Testing server. I took a screenshot of the nasty bugger and have attached it here. The Background File Activity window closes when the Put action results in no errors or warnings. That's fine, but EVERY SINGLE TIME I put an HTML file that has references to external files (**so ya know like ANY HTML FILE EVER**), the window stays up and requires me to take action on closing it. THIS IS EXTREMELY ANNOYING. The error message displayed in the window doesn't even seem to be accurate (- error occurred - Access denied. The file may not exist locally, may be open in another program, or there could be a local permission problem), because it DOES put the HTML file in question. Perhaps the worst characteristic of this window is that is floats above everything else on my desktop. That means if I want to do a local>remote sync or just upload a bigger bunch of files, and then jump back into Photoshop to keep working on assets in there, I eventually am interrupted by this window popping up. This thing is worse than my cat trying to lay on my hands when I'm typing.
So, if anyone has any suggestions on how to turn this frustrating dialogue off, I would be very grateful.
My system specs are: Yosemite (Mac OS 10.10.1) and Dreamweaver CC 2014.1 (15.0.0.6947).
MUCHO DANKES

its not FTP information, the site is defined as Local
Network. I have a drive
lets say M:\ mapped to \\machine\webroot or whatever and then
point my DW8 site
to M:\webroot
It can synchronize all it wants, all day long for all I
care...... just lose
the focus so I can switch windows??? You don't name something
'background' file
activity when its in your face and causing nothing to respond
appropriately in
the 'foreground' lol.

Windows Backup - The backup application coud not start due to an internal error: You must be logged on as an administrator to perform this task. (0x8100000010).

Windows 7 users in my domain are unable to configure or change backup settings. Users are able to open Control Panel > Backup and Restore, but when they click
Change settings, they receive the error: Windows Backup - The backup application coud not start due to an internal error: You must be logged on as an administrator to perform this task. (0x8100000010).
The same error is received when executing sdclt.exe /configure at the command prompt, regardless of whether the command prompt is launched using "run as administrator".
I've done significant testing, and have been able to determine that the local administrator account is able to configure backups before the computer is joined to the domain. Once the computer is joined to the domain, the local administrator account
and domain users who are in the local administrators group are no longer able to configure backup and restore. Domain administrators are able to configure backups.
This is a new issue, which began occuring sometime in the last 2 months. 3 months ago, users were able to configure backups without issue, and those computers with backups configured are still able to run their backups and do restores; however the
settings can no longer be changed.
Clearly something in the domain is doing this, but Group Policy has not been altered, and I can find no setting that would be doing this in any case. Any help is appreciated.

Hi,
So you mean you have tried different accounts in the local Administrator group and all of them failed?
If so, please check what group the local Administrator group belongs to? Does it belong to a group with limited privileges, such as the Guests group?
