Ok I've discovered that this only happens when RA refresh rate is set to anything but 60hz in the output section of RA's video settings. Having RA set to 165hz or 120hz PPSSPP crashes in fullscreen on boot. With it set to 60hz it does not crash with vulkan on boot.

I happen to have an 165hz 1440p Monitor..

And, going 60hz all the way to work arround it won't cut it !!

i have tried 50 and 60hz output in RA , and as soon you Toggle-fullscreen it crashes !! Starting in fullscreen however, won't crash RA... But going from full to window , boom → crash regardless of the refresh rate setting!

so then i have tried to reproduce the problem by setting everything to 60hz, desktop refresh rate included .. and the same keeps happening !!

Something happends when toggle / switch to fullscreen or back to windowed state !! And only with vulkan renderer, OpenGL isn't affected by this !!

For me the fix is to set the Windows scaling factor ("Make everything bigger" in Settings) to 100% (down from 150% in my case).

Sadly, setting retroarch.exe's "High DPI scaling override" compatibility setting to "Application" doesn't work, I have to set the overall OS scaling :(

@BParks21 @metagondria @genpfault Is it still an issue using latest update as there was some update about context cleanup ? Thank you.

It's better. RA will crash if I press F to go to window mode too quickly after launching a PSP game. If I wait a little longer then it doesn't crash RA. Or if I go in and out of fullscreen too quickly back to back it will crash. So doesn't seem completely stable.
