I can absolutely confirm your way to reproduce this bug. Hopefully this will help pinpointing the problem in compiz/unity. Hopefully one of the devs will look into this...
Just to make on thing clear: This bug also happens with multiple windows being invisible in spread. Sometimes I have like 10 windows invisible in gimp. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/963164 Title: windows sometimes appear invisible in spread To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/963164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
