Imac 27 "2020 glitches - AMD Radeon Pro 5700 XT 16 Go

[Daniquito]

Hi everyone, I'm experiencing this since a few weeks with my 2020 iMac 27 - AMD Radeon Pro 5700 XT 16 Go.

Sound remains ok when glitches come, but the iMac completely freezes and I must restart (hard reboot)
NVRAM, PRAM, SMC done but nothing changes.

Any help would be appreciated, thanks.

10.15.7 was supposed to fix this

It did not...
I'm very disappointed

Hopefully you can still exchange your unit because that's not normal. Sometimes hardware is just not 100%. Stress tests at the factory are supposed to weed them out, but maybe this one slipped thru

It only happens with Mainstage opened, otherwise never...
That's why I suppose it's software related, what do you think ?

sorry, no knowledge of the program, but good that's it's isolated
