Cemu

Mario Kart 8 crashes to desktop randomly after 5-15min of gameplay in 4P splitscreen mode, when using the 60FPS gfx pack.
I first noticed it on 1.20.2b and it does not happen with 1.19.3.
It is random and it can take anywhere from 5 to 15 minutes to happen but it does eventually.
It can happen in the middle of a race or when starting or ending one.
Happens with old or fresh cache files (all three types of cache), with and without async shader compilation.
It does not happen when playing in single player mode.
