I noticed something weird today with my MBP 14in M1 w/ 32GB of RAM. When trying to paint on a layer with the brush tool the brush tool will go up to the edge of the picture and completely stop or lag at the edge, until the mouse suddenly reappears on the other side of the screen (usually takes a couple seconds). Did not matter what brush size or hardness etc. I used or file size of the photo. I tried playing with settings, uninstalling wacom drivers, to no avial. Finally, I logged my wife's user account out and when I returned to photoshop I could use the brush tool again like normal. Curious why this might be? Is it just a resources issue with the computer? My wife is not a heavy app user and pretty much just leaves Chrome on, though I know chrome is a RAM hog. I have a work around so mostly curious if anyone knows WHY this happens or if there are specific performance settings in photoshop I should adjust that could help me in this situation. Thanks!
