it's fairly common, I get it 2/3 runs, it's hard to notice cause you want to stay away from enemies, It's usually after a combination of jumping and kicking. I'll try to get some game play footage. could the kicks be queuing, I find it can stop after a few kicks.
EDIT: sorry about the framerate, I don't have the best gif capture ever.
