Photoshop is flashing when moving the cursor

Question

Hey there,

I recently recognized a problem when using photoshop:

The top part of every picture I'm working on is flashing whenever I move the cursor (see attached video). If I zoom out a lot the problem is gone, but I need to zoom in to work on the picture.

I tried the following already;

- restart computer

- uninstall and reinstall photoshop

- update macOS

- make sure my photoshop is compatible with my CPU

- free up some space on my macbook

... non of these made a difference 😞

I don't know what else to try. It was working perfectly before and I only realized this problem now (did the macOS update after I realized the problem).

Does anyone have an idea what to do in order to fix the problem? I'm grateful for every idea cause I need photoshop on a regular basis for my job and I can't really use it like it is now 😞

Thanks in advance, Silke

HiLooks like it's a GPU related issue, you could try enabling this option in preferences and restarting Photoshop to see if it helpsIf that doesn't help try a preference reset

This was happening on my laptop and I thought I was going to go mad. Finally I realized it was because my Pshop window was open "beyond" the monitor frame. When I made it fit into the window, the flashing resolved. This happened because I accidentally switched to full screen mode and when hit "escape" to get out of full screen, it didn't reduce my window in proportion to my laptop monitor.
