AMDGPU Causing occasional X crash

I unfortunately can't pinpoint when this started, but it was recent. It happens when I go away from the computer. I don't suspend or anything, just have KDE set to sleep my monitors.

This seems similar, and is marked solved, but I can't find a 'kfd' module in the kernel that is mentioned. It's also the radeon driver. https://bbs.archlinux.org/viewtopic.php?id=232672

The Xorg error is

[240190.030] (WW) AMDGPU(0): flip queue failed: Device or resource busy
[240190.030] (WW) AMDGPU(0): Page flip failed: Device or resource busy
[240190.030] (EE) AMDGPU(0): present flip failed

with the full log at pastebin: for readability

Not what you want to here, but that arch error is unrelated as it deals with radon, not amdgpu, so kfd is most likely a wild goose chase.

However, it does appear that this is a known bug. link. Reading through, it appears it might be opengl and/or kwin related. I have experienced no such thing with i3, however I also disabled screen blanking. I have only turned my displays off once or twice but never with any issues.

For an experiment I would disable the kde power savings and see what X does if you let it decide what to do instead of some other black box. To set the time directly create a file /etc/X11/xorg.conf.d/40-monitor.conf and put
