[4.8.2] Oddly specific crash on Plutonia MAP06

[MFG38]

So I was just playing Plutonia casually and started getting crashes upon trying to enter the final area of MAP06 (Baron's Den). The crashes seemed to mostly occur when facing towards the center of the area - namely, approaching it while facing in its direction. What makes this crash interesting is that it only occurred when the game was running fullscreen - I was able to bypass it by running in windowed mode for the remainder of the map. But still, I felt this was worth reporting. I tried having GZDoom produce a crash log by adding the +logfile parameter once but it gave me nothing useful.

Possibly relevant information:
GPU: AMD onboard graphics (Ryzen 5600G)
Rendering backend on GZDoom: OpenGL
Screen resolution: 1920x1080
GZDoom fullscreen resolution: Native

What precisely did you get when it crashed?

What precisely did you get when it crashed?

The program just froze for about 5 seconds and then terminated itself. No error messages of any sort. If that's what you mean.

Okay, I may have found the cause of the crashing - it's likely related to the fuzz effect rendering being set to "Software" mode. Encountered the crash again on MAP08, similar results: game crashed when running in fullscreen but not in windowed mode. Just for the hell of it, I changed that setting to something else and back while looking at a Spectre corpse and that crashed the game again (game was running in fullscreen when I ran this experiment).

Please don't tell me that AMD has another shader miscompilation...
