I have somewhat similar symptoms, and I have found a [b]reliable way to reproduce them[/b]. It seems that [b]every time[/b] I minimize a window, it leads to severe graphical corruption and very strange behaviour in Unity.
A minimized window refuses to reappear when I press the launcher shortcut or top panel. Pressing Alt+Tab seems to be the only way to get it back, but it will have some severe graphical corruption when resized and moved around. See the attached video. Lenovo ThinkPad X200 with Intel 4500MHD graphics controller. Ubuntu 11.04 amd64 fully updated. Universe and multiverse repositories enabled. uname -srm: Linux 2.6.38-8-generic x86_64 If you need any additional info, like installed package list, changed configurations etc. please let me know. ** Attachment added: "Severe graphical corruption after minimizing windows in Unity" https://bugs.launchpad.net/unity/+bug/709461/+attachment/2143446/+files/Unity_minimize_bug003.ogv -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/709461 Title: Application windows can sometimes fail to display and will mask regions of the screen _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
