i restarted my computer a bit ago, and following this my zoom gestures in photoshop stopped working completely. i was able to fix it by selecting "zoom with scroll wheel" and "zoom resizes windows", but now zoom is extremely laggy and sometimes freezes up the whole program. i have "enable gestures" on and "GPU accelerator" on as well. nothing i've read in other questions similar to this has fixed the lag. any help is appreciated, thanks
edit: i've found that it zooms in and out normally in other files, it's only laggy in one file that i've been working on. there's only 3 layers and the canvas isn't very big (2000x2000 pixels) so i don't really understand what the issue is. i haven't used any brushes that typically lag the program either
