I am also seeing this on Ubuntu 8.10 64-bit, fully updated - I am also using the proprietary nvidia driver with an nvidia 7600GS with compiz enabled.
I think this is a bug in the proprietary nvidia driver as the recent 180.06 BETA driver claims to fix this problem: from: http://www.nvnews.net/vbulletin/showthread.php?t=123072 "Fixed a regression that could result in window decoration corruption when running Compiz using Geforce 6 and 7 series GPUs." -- Window border is drawed corrupted https://bugs.launchpad.net/bugs/287179 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
