pretty much the same here on 945GM When compiz enabled, when the mouse is moved the screen flickers (at about 25Hz) between a black buffer and the proper buffer that should be drawn, once the mouse stops it's pot luck whether it ends up on the black buffer or the proper one.
does this happen with any other 3D apps, perhaps? or just compiz? is there anything useful in dmesg or ~/.xsession-errors ? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers

This is from Eee PC 701 (i915GM) which has the same problem, using desktop-i386-20090915.15.iso. glxgears alone works fine. When compiz is enabled, this line appears in ~/.xsession-errors: compiz (video) - Warn: No 8 bit GLX pixmap format, disabling YV12 image format Sometimes compiz crashes immediately after enabling with this in dmesg: compiz[1869]: segfault at 7818a0 ip 007818a0 sp bfd729c0 error 4 in libxcb-aux.so.0.0.0[824000+2000] When compiz runs, it crashes after disabling. It's not visible to user, only this line appears in dmesg: compiz[1827]: segfault at 5e98a0 ip 005e98a0 sp bf8c4300 error 4 in libXext.so.6.4.0[653000+10000] or compiz[1889]: segfault at 53a8a0 ip 0053a8a0 sp bf87f9c0 error 4 in libSM.so.6.0.0[5c0000+7000] or compiz[1915]: segfault at 9f58a0 ip 009f58a0 sp bfbdc1a0 error 4 in libXrender.so.1.3.0[a34000+8000] or compiz[1938]: segfault at 2f08a0 ip 002f08a0 sp bfa0b010 error 4 (seems like random error generator :)
(In reply to comment #3) > pretty much the same here on 945GM Rawhide updates from 2009-09-19 fix this for me.
that's clever, it's not 2009-09-19 yet =) for those who can't install Rawhide, nightly live CDs are available here: http://alt.fedoraproject.org/pub/alt/nightly-composes/desktop/ so maybe try with the one from today or tomorrow or sunday and see if it works for you. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Updates to mesa on 19/09/2009 fixes it for me as well.
desktop-i386-20090917.16.iso does not fix this, maybe the next one will.
there's a 20090920 image up now, can you try that? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Both 20090920 and 20090921 do not boot: losetup: could not find any free loop device loop: can't get info on device /squashfs/LiveOS/ext3fs.img: Inappropriate ioctl for device losetup: could not find any free loop device loop: can't get info on device /overlay: Inappropriate ioctl for device Usage: blockdev -V [...blockdev usage text...]
yeah, I found that out later yesterday :/ stay tuned, we're working on it. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
It works fine with desktop-i386-20090927.16.iso on Eee PC 701 (i915GM).
Thanks! -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
