Slow batch paint strokes

I’m having that thing where you move your brush and the line slowly follows it. I can’t work. I’ve tried new project and user etc reboot, power cycle. All the tricks that usually work but … … this is in 2021.1.1 . in 2021.2.1 it’s fine, but I can’t use that version on this job. Anybody have any clues. Thanks

Sht. Of course I ask, and now I fix it. Seems like a bug though. I had the compare split swiper thingy up with a ref in the cache. Ctrl-B’d that and it works now. Bug. Nothing to see here.

Invoice yourself a beer. Good job.
