Something similar also happens to me since I installed Ubuntu 9.04 amd64 (clean installation).
OS: Ubuntu 9.04 amd64, up to date CPU: Intel Q6600 CPU System RAM: 8G Graphics card: 06:00.0 VGA compatible controller [0300]: nVidia Corporation GeForce 8600 GT [10de:0402] (rev a1) Video RAM: 256M RAM I'm using the proprietary nVidia drivers (v180), but it does not seem to be the cause. Reverting to the older v173 drivers does not change the situation. I'm using GNOME, but have to use KMail as well, since I've been using that for years and can't live without those filters and accounts. KMail is badly affected by repaint artifacts, unfortunately. I've also observed the same problem in SkyPE 2.1.0.47 and in the menus/context menus of Mozilla Firefox 3.0.14. I'm going to attach a screenshot of broken KMail mail list view. The bug is listed as "Fix Released" here, but updating my system does not solve the problem. Is there a way to get it fixed without completely upgrading to Karmic Koala? -- (Needs UXA) painting artifacts after qt4.5 upgrade on intel chipset https://bugs.launchpad.net/bugs/338669 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
