Karol, I believe this bug is caused by the compiz mipmapping code. So you should be able to work around it by:
1. Install compizconfig-settings-manager 2. Run ccsm 3. CCSM > Window Management > Application Switcher > General > Mipmap = OFF -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006216 Title: [nvidia] switcher+nvidia: Alt+Tab makes compiz hang and shows white preview windows To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1006216/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
