So we see this consistently, and it seems to happen (sometimes) when Chrome pops up a new window (I see it when gchat creates a mole, or when a link opens in a new tab, though not always). The size of the white box is the size of whatever window was being created.
The white box is not a window; X events go to whatever is "underneath" as if it weren't there, and xwininfo doesn't see it. Restarting compiz reliably makes it go away (but has other annoying side effects, like making the upper-right icons no longer responsive to input). As you can imagine, we have a lot of Chrome users, and this is a very significant usability problem for us. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940603 Title: white box randomly shows up at top left corner blocking applications from using stuff under it To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/940603/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
