Want to report that I've installed the swapfile tweak in hope to improve the stuttering issue. Well...it makes it worse. It stutter more frequent and longer. So I uninstalled it in hope that it'll go back to what it was before. Well...it didn't. After uninstalled the swapfile tweak, the stuttering is basically gone. That is a nice surprise. At least that's my experience. 1.14b (Feb 21), 59.00.504, Android 11.
