This is NOT a bug in the Assembler. File created by APNGASM 2.91 with 1/100 delay. Chrome has excessive delay between frames. I can play the APNG using the QtAPNG sample app, and it plays correctly.

Any suggestions to work around this feature of Chrome? Even trying 1/1000 did not have much effect. The animation is SLOOOW on the browser.

I think all browsers put a certain low limit on the animation delay. Last time I looked, that limit was hardcoded, so it can't be changed, I'm afraid.

It all started years ago because there was a lot of ancient GIFs at that time with "0" in the delay field, They didn't want to burden the CPU forcing it to play them as fast as possible, so they put a certain limit on how fast the animation can be played.
