I can confirm this bug too. I only installed 12.04 beta 2 on a clean hard disk yesterday (long story). (All updates installed -- am updating every few hours as I'm interested in how this release is progressing.) I use Chrome as well.
I'm not sure if it is only happening after coming back from the lock screen (auto-lock after leaving the machine alone for a while), but that's what it's felt like. Box is smaller in height for me than the screendump above. -- 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
