Weird visual glitches on Photoshop 21.2 when moving objects on Windows
I sure hope someone can help because I'm tearing my hair out in frustration! I've just upgraded to 2020 and have the latest version. Every time I move an object I can still see it in it's original location. I see it where it's moved to as well, but it's also still visible in the orginal spot. I have to turn the background layer on and off for it to disappear. Also, if I import a new object into a new layer over the original layer, the original layer's shadow effect doubles in darkness. I've also noticed that when I'm using the eraser tool I'll see the effect for the first few strokes, but then nothing. No pixels disappear. Again, in both instances, once I turn the background layer off and on then I'm seeing what I'm supposed to be seeing (what's actually there.) I'm sure I'm explaining this terribly but I did make an image so you can see a visual of what I'm taking about (minus the eraser tool effect.) I sure hope someone knows what's happening here because it's extremely frustrating and has basically halted my work over the last few days.
