I can fully reproduce it with any window (Unity 5.14.0, Compiz 0.9.7.8 - default settings) following these steps:
1) Minimize any window 2) Super+W (to show Scale) 3) Super+W (to hide it) 4) Click on the application icon in Launcher or browse to it using Alt+Tab / Alt+| Notes: - Minimizing the blank window and using Scale reverses it. - This issue does not happen when the app has 2 or more windows (which,again, triggers Scale) I hope this helps (= -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/729979 Title: [nvidia] Windows appear blank white To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/729979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
