Rojo, could you maybe submit another bit of code that either disables that feature or automatically sets whatever if there is only one frame or for paused animations?
I could submit a bug report or feature request but I think it would be on the backlog, whereas you may already know exactly where the issue is.
The following isn't a rant, just making my case for you to take the time:
Even when it doesn't affect caps to the point where people notice. Its cutting down the effeciency of almost every game since most game have single frame backgrounds, platforms, ui elements, etc.
It was a necessary fix, but its created another problem. The little bit of maintenence it seems to require becomes a problem with older caps when people wanna upgrade, or with noobs who don't know about it, or when you're building up a cap and it suddenly manifests itself, as there is no easy way to go through a crowded layout and make sure you got every last one. The alternative to manually set 1 frame animations to 0 speed every time is inconvenient and easy to forget
