A while ago I had dropped my tablet about 3 feet onto a cement surface, but for the most part, it still worked fine. However, I was doodling a bit last night, trying to draw something completely from scratch with it, rather than scanning inked linework. I noticed that if I had the image zoomed out to maybe 25-50%, and made a very long line, when I zoomed back in, it looked really jagged or zig-zagged, especially if I was only using a light stroke, rather than using more pressure. I just tried to see if the same thing happens with the mouse, and it does. Is this just a natural result of trying to make intricate lines in a zoomed out mode, or is there some setting in Photoshop/Painter I could change to fix it, or are both my mouse and tablet fubar-ed?
