Hey, I recently coded an md5 viewer using opengl + sdl2 in windows and have come across a really strange issue. My geometry kind of explodes on certain frames, so one of the first things i tried was disabling interpolation, which "fixed" my problem. I've been stuck on this for a couple of days now. I'm currently using a model and anim straight from doom 3 so I know they aren't corrupt.
Here's a vid of what's happening.
