I'm using photoshop on my brand new desktop and am seeing glitches while drawing that Ive never experienced on my laptop.
The 2 glitches -
Glitch 1. When using the zoom tool, I will see the vertical scroll bar move randomly, then my entire photoshop freezes...then disappears if I minimize the app. I have to close my file/reopen to get the canvas to display again. When viewing my video, you are able to see when I try to resize the window to fit the entire canvas, the vertical move bar on the right is moving (as if the canvas is resizing to fit the screen), but the canvas itself is frozen.
Glitch 2. The zoom tool sometimes flashes colors on the screen or flashes a grid.
I have no clue why these glithces are occuring. I tried uninstalling the latest PS and reinstalling old versions, but I kept seeing these problems happen with any version I tried.
