Hi @Deleted User ,
Many thanks for the screen recording. Looks like there could possibly be some GPU issues going on.
Do you have Deactivate Native Canvas checked in Photoshop's preferences > Technology Previews I wonder?
If not, does it help to check that option?
Give that a try, and when you can, please provide Photoshop's Help > System Info dialog text in this thread here and we'll take a look from there.
Regards,
Pete
