Why is mouse movement 10-30 fps looking with GPU support on in liquify?

I don't know if there's a fix or already a discussion and my search skill isn't strong on this platform/language.

------maybe irrelevant------

Lateste official release photoshop had laggy liquify on M2pro Mac mini.

I turn off/on GPU support as a diagnostic/bypass. (I decided to keep working on my m1 mini for photo)

------maybe irrelevant------

I noticed that mouse cursor is like 30-60fps smooth without GPU support OFF

If I turn GPU support ON the cursor behaves as if it's 10-30fps.

NOT jumping because it's lagging.

It skips a lot of frames in between moving points.

any ideas?
