This seems to be related to #153204. Could you check if the following workaround works for you?
Type the following line in a Terminal sudo apt-get install compizconfig-settings-manager Start Advance Desktop Effects Settings (System->Preferences->Advance Desktop Effects Settings). Click on "General Options" under "General", uncheck "Unredirect Fullscreen Windows" (should be 3rd from the bottom). Click on Back and Close. Does the flicking still happens? -- [Compiz-Fusion] Screen flickering while doing Alt+Tab when an application is in full screen mode https://bugs.launchpad.net/bugs/155053 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
