I thought it was my tablet but it seems to be something about photoshop, when i draw it looks to be making wobble lines but when i zoom in they look just normal i unistalled photoshop last update and instaled the previous one and that was the issue
i don't know if i am the only one that had this problem
What tablet are you using? I know sometimes when I used Sidecar to use the Desktop version of PS on my old Intel Macbook Pro, I'd have some wavy lines, but they disappeared after I just turned up smoothing slightly. The issue wasn't there when I used Astropad or when I use my Cintiq.
