dmesg output after GPU crash with "amdgpu: The CS has been rejected"

Might be related to bug 111860.

In my case, the GPU crashes or fails to resume when I use the Godot Engine FOSS application: https://github.com/godotengine/godot

The application works fine for a time, but eventually it will freeze and this gets printed to the terminal:

amdgpu: The CS has been rejected, see dmesg for more information (-2).
amdgpu: The CS has been rejected, see dmesg for more information (-19).

(attaching dmesg)

At this point, I have to kill the application, and reboot if I want to use the GPU again.

This seems to happen mainly when alt-tabbing between Godot and the desktop or terminal (both of which run on the Intel HD 630 IGP), so it might be an issue with context switching?

I don't have precise steps to reproduce yet apart from using Godot (debug build from git master branch) and other applications in parallel, to eventually see it crash within 5-10 min.

I think the bug started to happen when I upgraded to kernel 5.2.x (now running 5.3.2, still having the bug). That's what bug 111860 claims too, so I'll attempt running 5.1.20 for a while to see if the bug still happens.
