Created attachment 49944 [details] Look at digit '4' . This is part of Konversation chart - Some certain font letter drawn not correct over all system , meaning that if you see that '4' don't have it lower part than in any application that you will open you will same behavior . - After each system reboot new letter(s) became currupted . - Changing used font in "System Settings" can some times solve issue , but if you don't reboot system for a long time it can appear again - with "Force Fonts DPI " turned on there more artifacts in comparision to turned off this option

Sounds a bit like Bug #36326 ...
(In reply to comment #3) I review defect that you mention . Snapshot from defect looks very similar to problems that I have. Main differneces : - I use KDE against GNOME in Bug #36326 - I didn't detect any influence of font size changing But maybe this differences not important for root cause of the problem...
Created attachment 50090 [details] Icons curruptions in same environment Looks like problem was not hard linked with fonts . I attach new file - please look at icons in the tree they have same problem as letters ...
I've pushed a tree to remove some of the optimisations to see if they are the cause of the corruption: http://cgit.freedesktop.org/~ickle/xf86-video-intel #glyph-cache-bug Can you please try this branch to see if does the trick? Rough guide to testing: $ git clone git://people.freedesktop.org/~ickle/xf86-video-intel $ cd xf86-video-intel $ git checkout origin/glyph-cache-bug $ ./autogen.sh --prefix=/usr $ make $ sudo make install # restart X
