I've pushed a patch to KWin that should fix the problem. The patch is in both master and the 4.9 branch, so you should see it in 4.9.3. That release will be tagged on Thursday.
@Rune: The GLX backend in KWin uses glXGetFBConfigs(), so the ordering rules in the spec don't apply here. I've thought about rewriting that code to use glXChooseFBConfig(), but I'm reluctant to touch working code without a good reason. This bug might be enough of a reason to do that though. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1061073 Title: Desktop effects are slow and desktop corruption using mesa 9 To manage notifications about this bug go to: https://bugs.launchpad.net/kdebase-workspace/+bug/1061073/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
