Created attachment 8505463 [details] Firefox_bug.jpg User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0 Build ID: 20140923175406 Steps to reproduce: 1. Install Windows 2008 R2 Server with terminal services 2. Install Firefox 32.0.3 or 33.0.0 (also reproducable with older versions) 3. Connect to a terminal session using Windows Remotedesktop Client Actual results: Font displayed is pixelated (see screenshot). Using other browsers on the same system the font looks much smoother. Best anology I can give: it looks like anti-aliasing is missing or something Tried several websites, all of them were affected, although some are worse than other On a different system the tested websites are working fine
Could you paste "Graphics" section of about:support ?
And, Clould you try to set gfx.font_rendering.directwrite.enabled = true in about:config? (After you change the value, it is necessary to restart the brower)
Created attachment 8506748 [details] Firefox about support.JPG Added about:support Graphics section Error does not occur using teamviewer to connect to the server. Video card description in about:support changes to hyper-v video card when using teamviewer. Changing gfx.enable.direct.write did not fix the problem. I upgraded to Firefox 33 in the mean time, which did not solve the issue.
