Text runs off screen. Web page graphics have a triangle type 'border' applied at random around images edges. Text of menu elements includes pixelization with a crazy and random pattern. *It looks like my GPU would be dying, but all other apps work normally with the same pages, etc (including Chrome 9, 11 and IE 9). Reproducible: Always Steps to Reproduce: 1. Open Minefield 2. Cringe 3.

This is something to do with Direct2D I'm thinking. HTML and all web page text is fine...it's just the graphical elements that suffer. For example, this bug report page looks perfectly fine, while my menu bar has lotsa artifacts.

Could you see if the issue occurs with a new, empty profile: http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_make-a-new-profile Please can you paste the contents of the graphics section shown at the end of the about:support page - thanks! Also, try turning off hardware acceleration in prefs, restarting Minefield and then seeing if it still occurs.

Oh and screenshot please :-)

Please post the graphic section from about:support and mark it as dupe of bug 635463 if your graphic acceleration is disabled

Moreover, test against a 32-Bit Build of Firefox ....

32 bit works fine with latest build...64 bit still wonky Ill put up a screenshot...but to give an idea it looks like early direct2d efforts

screenshot here: http://gobliina.com/minefield64bugshots/Minefieldx64-artifacts-on-css-transformed-images.png Have tried following: 1. cycled (enable/disable) gpu acceleration... 2. disabled all add ons... 3. created new profile... To confirm this started after I applied build late in the night of 2/18/11. I have been applying updates daily for some time so it is build 20110219030201 that created the 'regression'.

Same x64 build on ati hd3870 gpu is fine...

Just to confirm it's the menu bar that's bad as well as any CSS transformed images (I also noticed it on CNN.com graphics which were rounded)
