I've recently upgraded to PS 2021 and noticed it has become almost unusable with the mouse stuttering every 3-4 seconds for about half a second each time. Trying to rotoscope things is impossible, How is this happening on a maxed out £5k iMac Pro? It's like going back 15 years.

As soon as PS is closed everything is fine. I hope theres a solution, it's beyond frustrating be going backwards.

Mouse is stuttery, lagging, making the app unusable. OInter stops and then appears somewhere else on screen. Also dragging the main app window bigger or smaller makes the entire active doc disappear.

For anyone wondering about this, I actually discovered I had direct Adobe support so I was able to talk to a real human in real time. For some reason PS 2021 was causing a problem with an external monitor I had connected but not switched on. As soon as PS started, this lagging with the mouse happened. Disconnecting it did fix the problem but new problems have arisen in 2021 for which no fix has been found: Re-sizing the window cuauses the entire document to disappear and using mask select properties causes the document to be split into 4 small boxes in the corner of the window making the tool unusable. 

I've gone back to 21.4 PS 2020 and all works fine again.

Mine does this exact thing! Must have changed the batteries in my mouse and keyboard 10 times thinking it was that. Hope they can get a fix sorted for it soon - will be returning to 2020 versions until then..
