I think I was able to reproduce this, but it's probably not a bug. As far as I
understand it, it's very easy to shoot yourself in the foot with the transform
mask. The bad behavior I got was huge memory consumption and unresponsiveness
due to transformation calculation. I'll attach a video below.
Repro:
1. Create a new document (big canvas and depth will likely make it worse).
2. Use the animation workspace
3. Scribble something on the canvas
4. Add a transform mask to the animated paint layer
5. Go to animation curves tab
6. Insert a control point, select Scale X or Y
7. Drag the point to a high value (e.g. Scale to 500%)
8. Open animation timeline and click on the paint layer
9. Start drawing again
10. Observe the memory usage go up
11. Keep drawing and using the UI, eventually the app will become unresponsive
when you try to switch the tabs.

(may be still processing, it should be 4K eventually)
Not sure about the status, I'll move it to confirmed, but please adjust as
necessary.
