So i've been tampering with APNGs recently as profile pictures.

No matter how short it is, it always has a lag at the beginning. Is there a fix or something? I try to make sure it's nothing crazy in size etc but the lag still persists (it smooths out after a few seconds but it's still weird).

I have a 4090 + 7800x3d, so it's defo not system related. What gives?
