Enabling hardware acceleration distorts website text in firefox 6

When using Aurora ver. 6.0a2 (2011-05-29) I have to disable hardware acceleration. When this setting is enabled, everything visible with the program (this includes the entire GUI, websites, all text & images) is distorted. It's not that you can't see the images or read the text at all, it just appears to not be rendered correctly. When acceleration is disabled, everything is returned to it's optimal viewability (for lack of a better term).
My current relevent system specs are:
Windows 7 Ultimate x64 (with all updates applied)
Video Card: AMD Radeon HD 6950
Video Card Driver: Catalyst ver. 11.5
Firefox Version: Aurora ver. 6.0a2 (2011-05-29)
Also of note, when using the official Firefox release (ver. 4.0.1), I do not have this problem. If you need any more information, I will be happy to provide it.

I have this problem with yahoo mail and Firefox 6 (no such problem with Firefox 5.0.1 and below). No other websites show this issue. When I disable hardware acceleration yahoo mail renders fine but with hardware acceleration it looks washed out in parts and patches.
System specs:
My current relevent system specs are:
Windows 7 Professional x86 (with all updates applied) Video Card: AMD Radeon HD 3870 Video Card Driver: Catalyst ver. 11.7 and 11.8

How to Enable Hardware Acceleration in FireFox 31

Please advise how to enable hardware acceleration in FireFox 31. All my graphics and other hardware/software is current and updated. I've also paired my Bookmark Toolbar down to under 20 entries.
FireFox is so sluggish that just a few open tabs cause the pausing "wheel of doom" every time I try to enter information or go to another part of the website. Sometimes the pauses are 5-10 seconds, sometimes a minute or more.
I do not have this issue on the other browsers that I use.
Thank you in advance for your help!

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can also check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Multiple_profile_files_created
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

Is there a way to have hardware acceleration without the text font change? + Eye straining firefox!

Is there a way to have hardware acceleration without the text font change? I remember there was a way to go into settings before and getting hardware acceleration to work without the font change. Unfortunately I lost ALL my previous setting when uninstalling the beta ver Nightly and clicking delete settings :(.
Also, I fixed a problem before where firefox was visually eye straining to me, I think it was some settings in anti-alias tuner, but I cant seem to find the right settings that puts less strain on my eyes, anyone know? Thanks ahead. Currently using FF7.

Try to toggle some Boolean gfx.font_rendering prefs on the about:config page to disable some features.<br />
Filter: gfx
Others to try:
* set gfx.direct2d.disabled to true to disable Direct2D
*Anti-Aliasing Tuner: https://addons.mozilla.org/firefox/addon/anti-aliasing-tuner/

Enabled hardware acceleration in version 33+ causing everything to render in solid black on Intel HD3000 (on both 2 years old and latest drivers).

Hello,
I'm experiencing troubles with Firefox versions 33+. Enabling hardware acceleration makes everything render in solid black, even on clean profile, even the "Choose profile" and "Firefox already running" dialogs.
Problem started when developers started to work on MSE.
Also the font rendering is doing wild things - some characters like 'l' (small L), 'i' and '-' at certain font sizes are not rendered at all and some characters like '=' are rendered partially like '-'. Of course with hardware acceleration disabled.
This is pretty annoying, because it appears in places I use a lot like address bar and youtube HTML5 player, leading to those render failures:
'Exit full screen' renders as 'Ex t fu screen'
or
'https://www.google.com/search?q=mozilla+firefox&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:unofficial&client=firefox-nightly&channel=fflb' renders as 'https://www.google.com/search?q-mozilla+firefox&ie-utf 8&oe=utf 8&aq-t&rls-org.mozilla:en-US:unofficial&client-firefox nightly&channel-fflb'
Is there anything I can do about it?
I've tried to update graphic drivers through my laptop manufacturer official sources and through intel's website, but neither did help.
Thanks.

I had the same thing with a nvidia gpu (660GTX) and ff nightly 33 .... every thing had big black pulsing borders like the css animations code had gone mental and the whole screen was flickery .. and all the text was clipping when scrolling creating trails .. I went into the gpu settings disabled acceleration and it worked perfectly after that so I can confirm that 3D accellerations has issue in 33.

How do I enable hardware acceleration in an air exe?

I have a Stage3d game compiled as a windows bundle (exe) using adt -target bundle. Users download it from Steam and have no idea it's even running Adobe AIR.
The problem is that if the user has manually disabled hardware acceleration in Firefox, it will also be disabled in my game. In these cases, context3d.driverInfo will say "Hw_disabled=userDisabled". If they open Firefox, right-click on a flash animation, open the security settings box and check "enable hardware acceleration", it will start working on my Adobe AIR game too. (note this isn't on all systems - I can't recreate the problem myself)
I would love to pop open the display tab of the security panel for them right in my game:
Security.showSettings(Security.DISPLAY);
But that command doesn't work in AIR, it only works in browser plugins.
Explaining to users how to enable hardware acceleration in FF, IE, Safari etc seems like a terrible, confusing solution.
Any better ideas?
(also, I think this might be a bug? can anyone point me to documentation saying firefox & air should share settings like this? I went to report it but the bug tracker's down as usual: http://bugs.adobe.com/flex/)

I found the correct/new link for the bugbase: https://bugbase.adobe.com
and posted this issue as bug 3843535:
https://bugbase.adobe.com/index.cfm?event=bug&id=3843535
It seems to be an unfortunately common problem which I would love to find a workaround for if anyone has any ideas. This would be easier if I could recreate it myself...

How to enable hardware acceleration in desktop Adobe AIR app

Hello,
As the author of this post How do I enable hardware acceleration in an air exe? , I am trying to enable hardware acceleration inside my AIR application
If the user has disabled hardware acceleration in his flash player's settings, context3d.driverInfo will say "Hw_disabled=userDisabled"
His only way to re-enable it is to open Internet Explorer or Firefox and right click on a flash content, then check "Enable hardware acceleration"
I (we) would like to be allowed to re-enable it directly inside the AIR app (via actionscript code) and not telling the user to open a browser and check some random checkboxes (cause you know it's not very user-friendly...)
A bug has been opened here Bug#3843535 - Disabling Hardware Acceleration in IE flash plugin disables it in AIR EXEs and is marked as fixed but nothing is fixed : there's still no way to enable hardware acceleration in desktop AIR application
Thanks

Hello,
I pushed to get this bug fixed and was under the impression that we addressed this back in v16. Can you share a sample app so I can have our team take a look?
Thanks,

Does the "Enable hardware acceleration" check box work in Google Chrome?

There have been some recent changes to the Flash Player "Enable hardware acceleration" tab in the settings dialog on Google Chrome. This tab is referenced in the How do I disable or enable hardware acceleration? FAQ.
You may have noticed that this tab was recently removed but is now present once again. We wanted to let you know that our intention for this setting on Chrome is to allow you to toggle hardware video decoding on and off. However, as of the current version of Flash Player (11.7.700.225) this is currently not enabled. While the check box will allow you to check and uncheck the box, nothing is actually occurring behind the scenes. We expect to correct this behavior in a upcoming release and will update this FAQ once completed.

No it's not. Gallium is a new architecture for writing drivers, and a bit more than that. Only softpipe and llvmpipe are software renderers, the others are hardware. If easyonthev is now seeing llvmpipe where he saw RV before, it indeed means he lost hardware rendering. I don't have experience with radeon cards though, so I don't know where to look for solutions. According to the log, everything loaded fine.
easyonthev, which graphic card exactly do you have? And are you using KMS or not?

Any wiki about enabling hardware acceleration on openssl?

Is there any wiki about how to enable hardware acceleration on openssl?
or does it just automatically happen?

Archwiki, or in general? The answer to either would be why do you want us to do your googling for you? I did a quick search for each option and took all of 5 seconds to have both answers. (edit: make that all three answers including whether it is "automatic").

Finaly. How to enable hardware acceleration for X-

After much discussion on this form and with my friends, I've finally cracked hardware acceleration for X-FI on Vista. It works by using Alchemy on a large scale and gives acceleration for everything you listen to. The breakthrough finally came through thanx to help and info I received from alexs3ds on this thread?http://forums.creative.com/creativel...message.id=645?It started as an emulation concept discussion and evolved in to this. It gives all your 3D audio effects and EAX in games without game by game transmutation and I have noticed a large quality and volume enhancement in normal music and film audio because even that is now accelerated. Here's a step by step guide on how to do it.[color="#ff0033">?[color="#3366ff">Download Alchemy and install. Get it here .[color="#3366ff">http://preview.creativelabs.com/alchemy/default.aspx[color="#3366ff">?[color="#3366ff">Open a?window in explorer and go to [color="#3333ff">Windows\System32.[color="#3366ff">?[color="#3366ff">Locate the file dsound.dll and right click on it then select properties.[color="#3366ff">?[color="#3366ff">Click the security tab then click advanced.[color="#3366ff">?[color="#3366ff">In the advanced security panel?that opens up, click the owner tab then edit.[color="#3366ff">?[color="#3366ff">Use this to set your user account name as owner.

Perhaps people who have it running on other versions of Vista could post this info and help put together a list. ?

It does work, however I discovered more?important conditions. You MUST have your audio card in game mode BEFORE you do this. The reason is that the alchemy file passes the audio to OpenAL in game mode only. IF YOU TRY TO RUN GAMES IN ANY OTHER MODE YOUR SYSTEM WILL CRASH WITH BSD. IF YOU TRY TO RUN MEDIA PLAYER IT WILL HANG. IF YOU RUN DIRECTX DIAGNOSTIC YOUR SYSTEM WILL CRASH WITH BSD. YOUR?CARD MUST BE IN GAME MODE. IF YOU TRY TO CHANGE TO GAME MODE AFTER THE SWITCH, YOU WILL NOT BE ABLE TO AS THE AUDIO PANEL WON'T LOAD. DO IT BEFORE YOU SWITCH. As for windows replacing files after reboot, that aint happening to me. I've looked everywhere and can't find any sign of?were replacement files would come form either. Not that I'm saying it isn't happening, Vista is supposed to have a security system that stops you from replacing core system files. It just ain't happening in my system. However, I do have various system hacks in place and one of them may be stopping this. Need to look in to this. Fact:- I'm sitting with this in system now ( got no intentions of going back cause the audio's great ). I've tested 0 up-to date games and all give EAX etc. Without transmutation. Audio sounds amazing compared to what it was before and video audio finely plays in sync ( hurray). Maybay I should add a warning to this mod that you must only try it if you know what you are?doing.BTW in case this has anything to do with it, my system is :-
Asus?am2 with nforce 4, amd am2 x2 dual core cpu, 2 gig dual channel ddr2 800, oem?SB X-FI and Vista 32 ultimate.

Mercury Playback Engine: software accel only for 5K Retina iMac, when would Adobe enable hardware acceleration???

Just curious when Adobe might be updating Premiere Pro CC list of support graphics cards for hardware accelaration.
The iMac 5K Retina has an optional upgraded AMD Radeon R9 M295X 4GB GDDR5 graphics card.
But this is apparently what happens in Premiere Pro CC when you start the program on an iMac Retina 5K with that graphics card: the hardware acceleration option is greyed out.

Looking at this, it doesn't seem that the Retina MacBook Pro's NVIDIA GeForce GT 650M is on the list. And the NVIDIA CUDA driver will give you nothing but heartache (a frequent source of kernel panics).
You might want to take your question to the Adobe Premiere discussion boad to see if there are any current 'workarounds' -> http://forums.adobe.com/community/premiere.

I cannot use the add text feature of my tripod website builder with firefox

I have a tripod website which I have had for years, I E, and Firefox no longer work to use the add text feature of the website builder at tripod. I tried Safari, but it isn't letting me put in a link in the text. Is there a way that firefox browser can help with this problem?

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Disabling hardware acceleration resolved issue with Google Maps not loading in Firefox 19

For the last few days noticed that I could no longer use Googlemaps in Firefox 19. The page would completely load then if I typed a single character into the search box for google maps it would bring up the "Still loading" text and do nothing.
Followed a couple links on the Mozilla support page and started Firefox in safemode. Maps was speedy and worked fine in safemode. I started again without safemode and tried the simplest step to see if it would resolve the issue and disabled hardware acceleration. All of a sudden maps worked again. The strange part is when I re-enabled hardware acceleration maps continued to work (go figure, makes no sense to me).
Just wanted to post my experience for others who may be having a similar problem.
System is Windows XP 32bit
Cheers.

Thanks for posting your solution. For other users who may find this thread and need more information, see:
