It's worth noting that the issue occurs mainly when using hardware cursors. kwin_wayland attaches gbm buffers to cursor planes, not dumb buffers. In addition to that, kwin_wayland avoids making atomic commits until the buffers become idle. We tested whether that could be culprit, but it seems that the issue is still reproducible. We cannot reproduce the issue when forcing software cursor, i.e. with KWIN_FORCE_SW_CURSOR=1 envvar set.
The issue happens randomly, but after it happens for the first time, it increases the probability that it is going to happen the next time.
