Mutter 3.36.0 works incorrectly on my RX 480 with 4k display
Affected version
Arch Linux mutter 3.36.0-1 xorg-server 1.20.7-1 xf86-video-amdgpu 19.1.0-1
Bug summary
On my primary 3840x2160 display, mutter now shows only in the top half of the screen. The bottom half of the screen is filled with garbage. The cursor also won't go past the middle of the screen.
Steps to reproduce
- Update Arch Linux to latest Gnome and Mutter 3.36.0.
- Attempt to log into XOrg session.
What happened
The session logs in, but the primary screen shows garbage below the center of the screen, and the cursor won't move past the top half of the screen, except to the other attached monitors.
What did you expect to happen
I expected the session to work as it usually did before the bug began occurring. It also already works properly in Wayland session.
