since today, I have problems with photoshop (I have been signed for several years and officially pay for this product). It is when you open the photography in the program that such color interference appears and it is impossible to do anything. The white rectangle appeared after I tried to change the color in this place. I downloaded the latest updates - it didn't help.
What are your specs - OS version, Graphics Card(s), Video RAM, etc.
This definitely looks like a video card issue.
Ηi! thanks forr help. windows10, Intel HD Graphics5500, NVIDIA GeForce 840M
