Comment 6 for bug 856138

Happening here too, running Oneiric final with latest updates. I've got the System76 Pangolin Performance (revision 7) with an ATI Mobility Radeon HD 4500 Series graphics card. The window decorations freeze in an either active or inactive state, not updating the title bar text and creating a confusing experience as several windows appear to have focus all at once. This consistently happens with nearly every single window I open; however, maximizing and restoring the window fixes it. If there's any information I can provide to help fix this problem, please let me know.
