@Daria5EAB Thanks for the video. Trying to reproduce here but haven't been able to. What else do you have installed or did you install on this new Win10 install? Do you use/install Wacom? Do you have gaming/high performance mouse with high polling rate?
One thing you can try to see if it resolves the issue for you is to go to Preferences > Technology Previews and check Deactivate Native Canvas. Quit Photoshop, relaunch and let me know if the problem still persists.
Also, in Photoshop, can you go to Help > System Info..., click Copy, open a text editor, create a new file, paste, save and attach that here please? Thanks!
