Hello, I've been enjoying animating with Krita, but I've noticed a weird problem that really screws up the timing of animatics.

When playing back what you've made, each frame seems to wait until its supposed to have ended before it displays, making it always one-frame behind. This isn't much of a problem for frame-by-frame animation, but when you're making animatics with variable-length frames, it really messes up the timing of things, no mater how much you adjust the keyframes.
This happens when hitting play on the timeline and just scrubbing by the timeline with your mouse. To get the correct frames to display, I have to click on each keyframe individually, and judge by looking at the length of the keyframe on the timeline if it's the right duration.

As I said before this isn't much of a big deal for frame-by-frame stuff, but I cant get to that phase of animating so easily if i'm having trouble with the timing of my animatics to begin with.

I'm using the Mac version, so I'm guessing that if Krita wasn't originally programmed for mac (which understandably, nothing is), something might not have ported over correctly, maybe having to do with indexes starting with one instead of zero or something along those lines, always hated that.

If I could get it fixed or get a temporary solution that would be greatly appreciated, as I'm trying to get into animation, and Krita has proven to be my best bet. Thank you.

This is known as a cosmetic problem on Macs and has been formally reported. The animation renders out to .mp4 ok (as far as I know).
I've no idea if and when it will be fixed.
