Drawing mode is back in GPU > Advanced
Just noticed this is back in Preferences:

I had to double check that I really was running the current version, since the "drawing mode" rolldown disappeared in version 22. But now in 22.1.1 it's back.
Was it just a glitch in the matrix? It's a useful workaround/diagnostic tool in case of GPU issues, so I'm glad it's back.
