panfrost midgard - major issues with MelonDS emulator - not able to trace properly too

@alyssa @bbrezillon @icecream95

folks, I had a severe issue with melonDS emulator, with soft render it works fine of course, but once I enable opengl the feast of glitches starts and my systems almost hang. tested on 2 different rk3399 platforms with completely different settings (DE, display protocol,etc)

the emulator is quite easy to compile, I tested main https://github.com/Arisotura/melonDS with mario kart DS. its the only decently performing DS emulator for arm linux so would be quite needed to have it not broken let say. I can identify that this behavior was quite similar like to monolith linux x86 game with box86. maybe @icecream95 can confirm that. #5680 (closed)

I wasnt able to get apitrace to work properly, it wasnt able to replay it nicely due some issue with the buffer (6894: warning: failed to map buffer).. So, I used SSR to record it at least, with mario kart for the DS as an example.
