RB6 on Big Sur Generated Visuals resource hogs

I just updated to Big Sur and noticed that when I load a track that doesn't have a video associated, the entire system is bogged down. 

Deck A - generated visual (no video associated)

Deck B - mp4 with a video

Playing the Deck B by itself, no problem

Playing deck A (even without it being displayed aka crossfader is on the right side) the deck B video becomes very choppy.

Play deck A by itself (nothing else playing) - generated visuals are choppy

The video for the file with an associated video gets affected so much that it's running around 10 fps while the generated visual is playing.  If you stop the generated visual, the playing deck with the video returns to normal frame rate.

If I play two videos, everything runs as expected without performance issues. I didn't have any issues prior to big Sur or the latest 6.5.1 RB.

I'm guessing it's a visual generator issue.
