Confirming this, using a Dell Latitude E5510 with Intel HD Graphics (on- chip), together with a docking station PR02X and a two-monitor-setup (2x BenQ GW2460, 1920x1080, DVI).
The problem occurs most of the time when scrolling in a full screen application on the left screen using the scroll bar (click the bar and move the mouse) while the mouse coursor leaves the screen during the scroll. This gives me a flackering or one of the screen goes black with a little random noise on the leftest ~50 pixels of the screen. This issue is new to me after upgrading from 14.04 with latest kernel 4.2 patches to 16.04 with kernel 4.4.0-28-generic. This issue is a regression as I'm still using exactly the same hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553503 Title: multi monitors - black flashes or black screen when the mouse cursor leaves a monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1553503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
