Hi @Jonah Lee Walker,

Thank you for making this report. What part of the Roto Brush workflow are you in went the warning dialog is shown? E.g making a selection on the base frame, making correction strokes on other frames, propagating the selection. Also, what is the resolution and length of the clip you're working on? Does this happen will all media or only certain clips? A screen recording would be extremely helpful as we try to diagnose what might be happening. System specs would be much appreciated as well.

Thanks very much for any additional information,

I have been making correction strokes on other frames. It is a complicated shot, and I am basically having to fix 5 spots every frame, and if I screw up and try and undo I get the issue.

The Footage is ProRes 4444, 3200 x 1800 shot on alexa (the lens wouldn't allow full 4K). The clip is 02:23:02 long at 23.976 though the Composition is only 6 seconds long.

I am on an iMac Pro with 3GZ 10-Core Intel Xeon, 64 GB of RAM, and a Radeon Pro Vega 64X 16 GB running Catalina 10.15.7.

I finished the corrections in 18.0.0 Build 39, but have another shot to do, so I will try that next and let you know if it happens, and see about recording it.
