One monitor freezes from time to time

I’m having an issue and I don’t really know where to start debugging it. I have a triple monitor setup, and from time to time (once or twice per week?) one of the monitors freezes, just displaying the last frame. This has usually happened when playing Final Fantasy XIV in full screen, though that’s a large enough part of my computer time that I’m not sure it’s exclusive to that. The system is otherwise responsive, and the game still runs fine, if I use Win-Shift-arrow keys to move it to one of the other monitors I can still play, but the main monitor is still frozen on the last frame. I also noticed when taking a screenshot with Spectacle in this state that it complained about not being able to talk to KWin (I think? I forgot to write down the error message). Is there any logs or anything in particular I should look at to try and debug this?
