Text and images appear corrupted, apparently cleartype or azure problem.

Posted

I get ugly and sometimes unreadable text. Images have the same kind or error, the anomaly seems like loss of vertical detail in web pages, but it's clearly not just that. http://img10.imageshack.us/img10/2066/mozillafirefoxbuild2013.jpg http://img692.imageshack.us/img692/6729/picasa3912013125242bmp.jpg To me, the issue seems to be with ClearType or more accurately, how Firefox deals with it, as no other program has this kind of problems. These are not related to my persona. I have no issues with text in menus or the program windows, but they do render a bit darker than in other programs.

Chosen solution

Try to disable hardware acceleration in Firefox.

Oh yeah, when the text is refreshed via selection and deselec, it clears up. Also, this happens in sections, in rows and paragraps even I just select a part of the text. Also scrolling a form with text in it makes empty row to be filled with the previous row's text sometimes.

Well, they went away I think. Haven't tested so much yet. I'll just use Chrome until the speed is better. It's about twice as fast as Firefox, which only does a bit smoother text... I don't read so much on this machine anyways.
