nvidia claims that this is is known issue with the window manager : "this is a duplicate of another Launchpad bug, and as I understand it, it’s a bug with Compiz and Mutter (the compositing managers of Unity and GNOME, respectively), see: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/269904. I believe it’s largely been fixed in Compiz, but that patch likely did not propagate to Ubuntu 12.04. I believe it’s in all Ubuntu versions >= 15.04, and probably is fixed in 14.04 as well (though not 14.10)."
so i'm afraid the only option is to upgrade to 15.04 (or maybe better 16.04) ... guess this ticket can be closed ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1503310 Title: window content doesn't refresh, only if window is moved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1503310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
