Recently my InDesign Program has been showing large blocks of either red or blue over my work area. Moving around the screen does not alleviate them like some other graphical glitches, I have to close the programme to remove them. No other programme is doing this.
InDesign has been particularly slow recently, lagging on new or small-sized documents.
I uninstalled the software and reset my preferences shortly after the first appearance of these blocks, however, they seem persistent. Any thoughts on what could be the problem?
