This isn't a bug, this is a feature difference between X11 and Wayland. The
monitor refresh cycle on 60hz is long enough (~16ms) that the act of holding
back a frame for one or more refresh cycles to make sure they are perfect
results in easily humanly discernible lag and is the source of most of the
input latency on a standard office PC or laptop. I don't know how much you are
buffering, but you are not going to be able to optimize enough to remove the
perceptible difference while keeping your frames clean. It is a sacrifice that
all modern desktop compositors knowingly make. High-refresh rate monitors just
brute-force the problem by having more refreshes.
