Installed related packages kwin-4.5.0-493.4.x86_64 (KDE:KDE4:Factory:Desktop)

project doesn't exist. I've updated KDE4 to 4.5 from KDE:Distro:Factory/openSUSE_11.3 instead. --> kwin-4.5.0-493.4.i586

kernel-desktop-2.6.35.1-3.1.x86_64 (Kernel:HEAD)

Meanwhile no longer available. 2.6.36-rc2 give me a blank screen (KMS broken?), so I've installed the update kernel for 11.3 instead. kernel-desktop-2.6.34.4-0.1.1.i586 Anyway, I can't reproduce that issue at all on my GM45 machine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have this problem in .36 from Kernel:HEAD too. It's independent on kernel/X version.

kernel-desktop-2.6.34.4-0.1.1.i586

Anyway, I can't reproduce that issue at all on my GM45 machine.

That's sad (In reply to comment #10)

The patch is for a later Mesa version. For now I'm going to apply my patch and provide you a package for testing, since I can't reproduce the issue.

OK, I'll retest it asap. Thanks a lot. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The main problem is very probably the fact GetGLXDRIDrawable returns NULL, which should not happen. Sorry, I do not understand the details, but the bug might be still in kwin if it use the DRI2 drawables incorrectly.
