Hi, I use Fedora 17 and as soon as kernel 3.5 has been distributed, I get very bad rendering artifacts on my laptop. The laptop is a Thinkpad R50 with a radeon graphics card 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02) It is not a new laptop, about 8 years old. I've opened a bug at Fedora where you can see 2 pictures of what happens. https://bugzilla.redhat.com/show_bug.cgi?id=845639 Reading the mailing list, I cannot understand if this problem has already been reported. I've tried to bisect but I've hit a series of unbootable kernels. "git bisect visualize" currently shows the log between BAD: be122ab Merge tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6 GOOD: c10e408 i915: Add option to bypass vbt table. where I can see a lot of drm related changes.
