i see the same behavior (slowness, artifacts). moreover, when using "kwin_gles" instead of "kwin" the screen does not seem to be re-drawn correctly. for example, invoking the "run command interface" starts to show it but does not finish the animation. the result is that you type but don't see what you type. finally, turning off "use opengl 2 shaders" in the effects-config doesn't change anything either (neither for "kwin_gles" nor "kwin").
i hope this helps in some way to narrow down the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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/ubuntu/+source/mesa/+bug/1061073/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
