As some of you know, I'm developing a game engine in C, and I came across a problem that left me kind of lost. When I was developing my collision system, I saw something very strange in one of the collisions. During the collision, a white line appeared, well to the legs of the sprite. I have no idea why. I'm using OpenGL 3.3, without additional use of third-party libraries. Before the collision system, I never noticed that, so I think there's something to it. Anyone know what it could be?
NOTE: The sprite that presented the problem was the sprite of the player that moves, in time 1:07. I could not cut the video, because for some reason the video editor sums up with the bug when it rendered the video (maybe because it was small it took as a noise). If you can not see it, reduce the speed to 0.25 on youtube and set to 720p to leave the sharp image!
Thanks to all who can help me!
responding to user1118321:
there is the print, it's very subtle, it appears quickly in one of the frames underneath the player. The problem does not seem to be the sprite, because in the surrounding frames, the "white line" does not appear, only at that specific point, and it is a bug that does not always appear, have to try many times to be able to reproduce again
