Playback animation speed doesn't match with gif animation speed

Here's a little comparasion I made, you can see they get unsynced

Playback seems to be about 20% slower. I think Pyxel either plays the animation a bit too slowly or exports the animation sped up, but I think it's the first

Hope it get fixed soon!
