I have similar (maybe same) problem... My character's glitch is showing parts of other skins that are on the same .png, but when i export only one skin - blinking occurs. Can I see your code? Maybe it is like mine 😃
EDIT:
I have few spine characters too but only (main) one make glitches.

I started a thread when I described my problem.
Animation blends and glitches on SetAnimation
I found out that problem is related to CPU power.
In editor - few glitches
On my android device - many glitches
On other android device, more powerful than mine - few glitches
Also when I start Chrome for example more glitches occur in editor. I am very confused with this problem.
