I've discovered a bug wherein when either run-ahead or preemptive frame latency settings are enabled for Mesen-S and the Super Gameboy or Super Gameboy 2 modes are in use, the games will both freeze and scramble graphics after roughly 30 seconds of gameplay. I tested this on both the 64-Bit Windows and Steam versions of RetroArch, and could get the behavior to stop by disabling either of the settings. I also confirmed my ROM dumps were valid. Tested on both Donkey Kong and Kirby's Dream Land 2.
