I can confirm this. What is not emphasized in the bug description is that the "invisible window" blocks any mouse clicks to the portion of the screen it covers. This is extremely annoying, as every time you minimize a window to get at whatever's behind it you become unable to interact with the windows you were trying to reveal.
>From experimenting, it seems that mouse clicks to the region where the now-minimized window was do not result in any mouse clicks being sent to the minimized window's application. However, such mouse clicks *do* get processed by the window decoration. For example, it is possible to minimize a window, then click on the space where the window's maximize button was, then un-minimize the window, and it will now be maximized. When I attempted to minimize Thunderbird and then hit its now-invisible X button to close the window, compiz crashed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/850458 Title: Minimizing windows in Oneiric cause invisible windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/850458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
