Hmm, that is not what I was expecting with 'bad glyphs on g33'. Can you please test with https://bugs.freedesktop.org/attachment.cgi?id=67912 ?
Jiri, do you mind periodically retesting with new kernels and reporting if you see the glitch again? If I am right about it being the cpu-relocs as will gm45/ilk, the issue should disappear with 3.7.
(On the other hand, it could just be that UXA scrambles glyphs on g33, as we have a large number of reports to that effect - except that this corruption looks different.)
(In reply to comment #4) > (On the other hand, it could just be that UXA scrambles glyphs on g33, as we I am back on sna for some time and the mangled glyphs are gone. This is UXA specific I'd say, I haven't seen after the switch.
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
