Description

Some weird problems happening with mupen for the pi:
super mario 64
gln64 + dynamic_recompiler = works
glide64 + dynamic_recompiler = black screen after every frame
Oot
gln64 + dynamic_recompiler = hangs complety (can't close RA)
glide64 + dynamic_recompiler = kinda just works
Majoras Mask
gln64 + dynamic_recompiler = hangs complety (can't close RA)
glide64 + dynamic_recompiler = kinda just works
Paper Mario
gln64 + dynamic_recompiler = works first but hangs after intro (can't get to select file menu)
glide64 + dynamic_recompiler = kinda works like super mario64 with a black frame after every frame perfect for epileptics

With frame duping deactivated the screen flickering stops,the screen stays black then.FPS count tells me that without frame duping there is around 1fps (showing the black screen).

When pausing (rgui) a flickering or black screen (bug) you always get the right frame as background

Research direction

Reproduce the listed Super Mario 64, Oot, Majora's Mask, and Paper Mario cases on Raspberry Pi with gln64 and Glide64 plus dynamic_recompiler. Compare behavior with frame duping enabled and disabled, and when pausing in rgui; done means the black frames, flickering, and hangs are resolved for the affected combinations.
