I'm looking for an explanation as to why my artboards always end up looking like in the picture attached when their background is set to transparent. The edges are also glitchy when I zoom in or out, or move layers. This is an absolute nightmare, I've tried everything: going back to previous versions, it works for a while, then it turns like this.
After a few days, the problem is still here, it will work when I erase the folder and open PS, but if I close it and reopen it again, the problem is back. I don't change any settings or parameters. What is going on ?
