I can confirm that the problem is present with both the intel and the modesetting driver on Braswell systems. The exact symptoms differ for each, but in both cases it is triggered when the mouse touches the left limit of the screen. With modesetting, it seems to "stick" until you move the mouse away from the left side. With intel, touching the left side starts a flickering that persists even after you move the mouse away. Mainly, just the mouse cursor flickers, but the whole screen will flicker when doing graphics intensive tasks like fullscreen video or gaming. Sometimes, the mouse flicker can be so bad it becomes nearly invisible.
I have made full report on the bug report thread opened by Salvatore. The good news is I found a workaround, you can use xrandr to scale the display to 0.9999x0.9999 and this prevents the issues in both intel and modesetting. This can be done in your .xprofile in your home directory to take effect at login. It does come with a slight performance penalty, but it's preferable to the glitching that happens otherwise (at least until someone fixes the regression). xrandr --output HDMI-3 --mode 1920x1080 --scale 0.9999x0.9999 Replace "HDMI-3" with the name of your display (can be found by running xrandr with no options). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1767654 Title: [Intel Braswell] Cursor gets stuck on left side of the screen To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1767654/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
