I noticed this on Wikipedia and it seems to change from greyscale to cleartype aa
I can confirm that and I noticed this on Wikipedia, too. I see this change from greyscale AA to cleartype when hovering the links. The rest of the text is in greyscale AA and not cleartype as it should be. Has this anything to do with Bug 686782 ? Are you using an Nvidia graphics chip? Btw. whis is the platform flag saying x86 Mac OS X?

(In reply to redsign from comment #1) > Are you using an Nvidia graphics > chip? Yes, I see this on Nvidia hardware
OS: Mac OS X → Windows 8
Oh boy, the title already says that this occurs with nvidia hw ... I am using an GT 520 btw.

I also see this virtually everywhere.

I can confirm that this happens on all cards and is not a driver issue. I can reproduce it on an Nvidia, 2 Intel machines, 1 ATI machine, and even (new in Windows 8) the WARP software emulation basic display driver with Direct2D forced on. There is probably someplace in the rendering code where Direct2D loses the text rendering parameters, or it isn't being set in a render target to begin with. Every single BeginDraw should probably follow with having the text rendering mode set.

Temporary fix: Head to - about:config and search for - gfx.direct2d.disabled - set to "TRUE"

Tested Fix on Aurora/Firefox/Beta - Windows 8 - Seems to fix the issue - Though it's enabled on Windows 7 (That's my second OS) and the rendering seems to be fine so it must be a driver issue.

Here are more reproducible steps that may be useful to finding what is causing the problem: 1) Go here: http://en.wikipedia.org/wiki/Scrum_%28development%29 2) Notice that the text looks okay at this point. 3) See the bolded word "Scrum" in the first paragraph? Triple click it. This should highlight the whole paragraph, and also convert it to using poor font rendering. 4) To more easily see the bad font, single click that bolded word "Scrum" once. Now you can clearly see the poorly rendered font of the first paragraph, as compared to the other paragraphs. Hopefully this might help you guys narrow down what's actually causing the issue -- and fix it!

I can reproduce this using the example mentioned above on Windows 8 Pro RTM (6.2.9200) with a GTX 580 using driver 302.82 WHQL or 306.02 Beta. So it's still happening on RTM.

This happens as well with ATI cards. Disabling Direct2D fixes it - text is then rendered on pages using Cleartype. Text on the tabs, meanwhile, uses greyscale font smoothing which looks poor in comparison!
