Hi! I did some tests on your files and sadly I cannot reproduce it with your
files, but I on an extra big canvas... I got the same results on the first
playback, on the second playback I could see the animation totally smooth. This
only happens on very large canvases and it seems its reaching the limits of the
hardware.

I tested some other configurations, with smaller and bigger images and I could
not reproduce it, then I went back to my original failing test image and I
could not reproduce it either there. From what I gather krita animation
playback is CPU intensive the bigger it is and this starts to compete for
resource with other programs, make it drop animation frames on some workloads.

For testing I recorded with OBS at 60ish fps - software rendering, and was able
to record the issue, however without obs software workload the issue is
non-existant. This is on an M1 mac Mini.

Just for the record, could you share the info at "Help ->  Show system
information for bug reports"?
