Issues:

- Display's native resolution of 3072x1920 (16:10) is unusable. The bottom of the screen creates artifacts every time I move my mouse there. Visually look like horizontal black lines and I am unable to use the bottom portion of the screen.
- Using the system, some times the whole screen becomes frozen with graphical artifacts. it then resets, and apparently resumes to normal.

Current workaround for both issues is to lower the resolution. Tested working ok with 2560x1600 (16:10) and 1920x122 (16:10)

Xorg

- If i turn off my internal display, the whole UI freezes. I need to drop to tty to reboot. Then after reboot, only internal display is working, and if I try to enable external display, I get an error reporting there might be an hardware problem. Tested with external display with multiple HDMI cables through a dell thunderbolt dock, and directly connected to laptop.
- If i turn off my internal display and only use external display connected to HDMI, Gnome shell on secondary display connected via HDMI becomes very slow and laggy. I have a hard time reproducing this as the secondary display usually becomes unusable.

Temporary workaround:
Reverting to nvidia-graphics-drivers-515 solves all my issues. None of the issues reported above can be reproduced on 515.

Status changed to 'Confirmed' because the bug affects multiple users.

wayland:

The graphics corruption and freezes should be fully covered by bug 2007668. Because it's the Intel GPU wired to the laptop screen.

Xorg:

The OEM team is tracking what sounds like that issue in bug 2009767. And bug 2007079 sounds the same.
