Somthing that happens no matter what version of photoshop I'm in, this bizzare extending edge happens when you zoom in too close or get the artboard too close to the edge. Has anyone else experienced somthing simlar? I'm using a windows PC also.
Turned off Overscroll and reopened it and it is still there. Somthing I tried to highlight here is that it also happens to things like the rulers, or the selection boxes. (used a diffrent photo to show whats happening better.)
