Stains with all images

[Emanes]

Hello,

I am trying to use PS but every photo that I open is showing with this stains:

Can anyone please help me?

Hello.

This looks more like something is blocking Ps since it extends beyond the edge of the canvas.

Have you tried the usual remedies? Resetting prefs? Re-installing? Contacting Adobe?

What version of Ps is this and where did you get it?

Maybe try selecting/deselecting checkmark with use of graphic card in Settings>Performance because for me it looks like Graphic card problem like corrupted driver or something.

Or update/reinstall video card driver.
