@Jan Girlich: I get "direct rendering: Yes", but I still experience low framerates for glxgrears.
I use Kwin, not compiz. After I turned off all effects, I see no more artifacts, however - with them on, I could see quite a bit in addition to the effects being absurdly slow. In particular, when I opened a new window, I just got interference pixels until the proper window showed up. -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
