Yes, constantly. Still have some black images while different in-framerates (during/in combination with a pro keyer filter - after some time of streaming/recording on MacOS 12.1). And some layers show black images after reconfiguring BMD-sources Desktop Video 12.2.2. But, most of the sources work as intended now. And the black-layer-bug can be workarounded by saving, closing, reopening.
It seems to be that the layer-does-not-show-content-except-next-to-the-video-selector-bug is described here: Monterey 12.2 - video in Mimo no longer working!
I think it was introduced in 6b6. (And on Monterey 12.2) any Video is dead. Currently I check the intel-Chip-Set, I’ll post an update later.)
Edit: My intel-device is not affected. M1-macBookAir and M1-macBookPro-13 inch are also not affected.
