Over the past month I've encountered a problem with Photoshop. Any time I make an addition or alteration to a document, whatever I've done does not appear until I zoom in or out of the image. I have also tried waiting a few seconds to see if the program just lagged but it still doesn't appear until I zoom in or out. An example would be if I add text to a document, while I'm typing the cursor will move as I type but the text doesn't appear until I zoom or move the page around. The system I work on belongs to the company I work for and is running a windows 10 and I've already had a tech come out and update all drivers. Does anyone have any ideas or any experience with this?
