Hi there,

 Recently my Photoshop started displaying weird lines and weird recurring shapes, that are somewhat rectangular or squares, these shapes appear on any image that I open. How can I fix this?

thanks

First Update your video card drivers, and if this doesn't work then you will have to disable OpenGL Drawing from Edit->Preferences->Performance
