White flash screen when using eraser and brush

[#1]

Hello To All,

I have been facing a problem with Photoshop CC19 20.0.3 with my Mac. It has been working fine since 2 days. When i tried to erase something or draw something with the brush there is a white screen that appear. I can't find anything on this. I already tried to change the performances setup (Drawing mode in Basic)

I don't really know if it's clear, Thanks in advance for your help !

I've been having the exact same issue ever since updating my Mac to Big Sur. I tried installing the latest update for my Mac to see if Apple addressed it, and no such luck. Did you ever find a fix?

Hi ! 

Yes I find the solution ! well at least it's working for me. I just reset the preferences. For this : https://www.photoshopessentials.com/basics/reset-photoshop-preferences/
