User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7 Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7 Text, menu, and UI elements are blurred from Morphological Anti Aliasing (MLAA) when it and hardware acceleration are enabled. Disabling either MLAA or hardware acceleration will remove the problem but is not an ideal solution. Reproducible: Always Steps to Reproduce: 1. Requires an ATI/AMD Radeon HD 5000- or 6000-series graphics card and the Catalyst 10.10e drivers. 2. Enable Morphological Anti Aliasing through the Catalyst Control Center under the menu Graphics>3D and check "Morphological Filtering" under the AA or All tab. 3. Start Firefox 4 Beta with hardware acceleration enabled. Actual Results: Edges of text, menu, and UI elements are smoothed out. In some cases inconsistently resulting in rough and jagged edges. Expected Results: Text and edges of menus and UI elements should be straight and clearly defined. Morphological Anti Aliasing (MLAA) is a new feature for AMD graphics cards that is a post processing filter that smooths rough edges that occurs from rendering 3D models in video games. However, MLAA does not at the moment differentiate between rendered game models and UI and menu items including text. The same effect is occurring here. The problem was far more severe under Beta 6 where the browser and web pages were more severely blurred and were unrecognizable but Beta 7 made it more tolerable. Disabling either hardware acceleration or MLAA removes the problem but is not ideal. Doing the former is tedious and is a nice feature to have for video games. Doing the latter negates a feature of Firefox 4. Internet Explorer 9 Beta, despite having hardware acceleration as well, is not effected by Morphological Anti Aliasing.

Hrm, I suppose there must be a sort of flag we can set to disable the filter, I wonder what it is.

We probably need to fix this. Kev, we'll need someone at AMD to tell us how to disable or cause us not to be affected by MLAA.

Place to start with this is gpudriverdevsupport@amd.com Still working on getting us some formal contacts, but that's a good starting point.

From comms exchanged with AMD, this is not something that can be user-controlled. What AMD can do is add an application profile entry for Firefox in the Catalyst Control Center to disable MLAA from being applied to the application. AMD will file a bug to make it so, and they've been given beta7 as an example. If more info is required, I'll update the bug, but this looks like it's out of our hands.

I was afraid of this. IE9 must be in the default profile.

Can they also add Seamonkey.exe to that list ?

I'm not sure whether I experience the same bug, as I have an ATI Radeon HD 3600. Unter Windows 7 32-bit with the default driver that comes with Windows, FireFox 4 looks fine, however WebGl doesn't work. Therefore, I installed the most recent Catalyst driver from ATI (I chose not to install the Catalyst Control center). With this driver WebGl works, but fonts look very blurry. This can be fixed by disabling 2d hardware acceleration in FireFox. In my FireFox DirectWrite was disabled by default, enabling it makes no difference. Here's the grapics section from about:support: Karten-Beschreibung ATI Radeon HD 3600 Series Vendor-ID 1002 Geräte-ID 9598 Karten-Ram 512 Karten-Treiber aticfx32 aticfx32 atiumdag atidxx32 atiumdva Treiber-Version8.821.0.0 Treiber-Datum1-26-2011 Direct2D aktiviert false DirectWrite aktiviert false (6.1.7600.16763, font cache n/a) WebGL-Renderer Google Inc. -- ANGLE -- OpenGL ES 2.0 (ANGLE 0.0.0.541) GPU-beschleunigte Fenster2/2 Direct3D 9

Issue reported on a French board about overclocking, GPU etc: http://www.octeam.fr/forum/index.php?topic=2800.0 Other programs are affected too.

I think I have the same issue with Thunderbird 9; it did not occur with Thunderbird 8. Screenshot of distortion in font rendering of message pane & folder tree in Thunderbird 9 with gfx.font_rendering.directwrite.enabled set to true Not included in the screenshot: message text is not distorted.

Same situation 583875, but then with directwrite disabled: no distortion observed.

With the latest driver update (http://store.steampowered.com/news/7553/) you can assign per application settings by pointing to their .exe files. This way I have managed to turn morphological filtering off only for firefox.exe and keep it on for everything else. Can anyone confirm this?

Is this bug tracking for AMD only? This blurring problem also happens to Intel HD Graphics as well if I turn on Conservative Morphologically Anti-Aliasing (CMAA). Should I file this Intel-related driver feature issue as a separate new bug or I just follow this one?

As this bug is 5 years and it's about AMD's MAA, I think you can file a new bug about Intel and linked to this one.
