Monitor Hotplug Issues in Cinnamon/X11

I didn't see any forum topics about support request etiquette, so my apologies if there's any important info I'm neglecting to provide.

It seems that one of my monitors is causing hotplug issues whenever it goes into energy saving mode, such as waking displays back up after the system is idle long enough to suspend them, freezing up the system for several seconds when turned off and then back on, or causing all of my desktop windows to get moved over to it when waking the system from sleep.

I've tried searching online for solutions, and it looks like there used to be actionable solutions in Cinnamon (such as changing things with gnome-settings or disabling the xrandr daemon from running) but I can't find any that seem to be applicable for modern versions. This issue doesn't seem limited to Cinnamon either, I experienced it in a previous KDE/Wayland installation, but Cinnamon seems like it might have something I can use to actually fix it.

The offending monitor is a cheap Sceptre LED model, but it behaves completely normally outside of these issues.

Has anyone else experienced an issue like this? Is this something that's been fixed in XLibre? Because I'm still using standard X11 at the moment.

I'm on kernel 6.15.5-artix1-1 with an AMD RX7600 using the latest Mesa and amdgpu drivers.

You have to rule out things, one at a time. I'm on Xlibre/MATE and I changed my old 19" 1280x1024 monitor with an even older 20" 1600x1200 one while suspended. Resumed the box, it worked like a charm.

I've only had this issue since I started using the Sceptre monitor, so I'm guessing the way it goes into power saving mode is seen by the system similarly to unplugging it for some reason.
