background turned greenish?

Hello, everyone!

For some reason backgrounds of color pallete, tools, new documnets, everything - has turned greensih? I can`t use the software at all, does anyone know what I`m talking about? So, for example, the hue ring and saturation/value triangle, set to display rgb colors, can not display porper colors at all; it`s all kind of dimmed with this green color.

I reinstalled the Painter, but to no avail...

I can`t use the software at all, does anyone what could this be?

Thank you!
