When running UXA (SNA disabled), there are sometimes glyph and pixmap corruptions/rendering problems. A OGV/Theora video to demonstrate: http://tnsp.org/~ccr/intel-gfx/uxa-bugs.ogv I suspect that this may be related to the Google Maps tile drawing corruption. Earlier report https://bugs.freedesktop.org/show_bug.cgi?id=37782 with similar problems, also with UXA. -- Window manager: WindowMaker 0.92 (also present with Compiz, so probably not WM related) -- chipset: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) -- system architecture: i686 / 32bit -- xf86-video-intel: GIT 7e09babb3e9e23882db30ee7d0c22c503962faa9 -- xserver: X.Org X Server 1.12.1 from Debian unstable -- mesa: 8.0.2-2 from Debian unstable -- libpixman: 0.25.2-1 -- libdrm version: 2.4.33-1 -- kernel version: 3.3.4 (vanilla from kernel.org) -- Linux distribution: Debian Testing aka Wheezy -- Machine or mobo model: Asus P5KPL-CM -- Display connector: VGA
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
