I recently downloaded klwp and I’ve liked it a lot because it centers my wallpaper and my One Plus 15 has an issue centering the wallpaper with scroll. I added it as a picture through the app and adjusted the dimensions because the centering was still as issue as a background. After using it for a bit I noticed that the scroll was a bit choppy, is there any setting or something I can do through the app to smooth it out?
Try going to KLWP’s app settings >> Advanced options - turn on “Disable Parallel Rendering” and see if that will work for you.
