Since updating to version 23.5, I've noticed a couple things. There seems to habe been some kind of change to how brush input is being rendered. On the plus side, it appears to have slightly reduced latency, but there is also some kind of bug causing a flickering to happen as the tiles are drawn in. Its really strange, the flickering while drawing is accompanied by it sometimes taking a step "back" in its history, only for that step to reappear as I continue to draw. I tried disabling multithread compositing to see if that was causing the issue, but it didn't make a change. Also, the same flickering behavior is there whether drawing with the pen or the mouse, so it seems to be about rendering rather than the input method.
Just to be sure, I reinstalled 23.42 and the issue was gone. Then, I reinstalled 23.5 and it was back.
Hoping this is solved in a patch soon, because I really like 23.5 and think with this bug solved, the experience / general input latency while drawing has potentially been improved. The bug seems specifically tied to rendering input, which is encouraging because any added fluidity is a good thing while painting in Photoshop. The problem may be driver releated to my Nvidia card, or the fact that I'm running the latest version of Windows 11, but it is definitely unique to 23.5 for me.
