When I play a game, every time the preview animations play again the HUD disappears for a split second but aside from that, gameplay is fine.

But when I go to watch a replay, it feels like I'm watching in 1 fps and everything stutters, unless I turn on hitboxes.

None of this happened the one time the game didn't stutter with replays. I still don't know the cause or at least a fix so I don't need to have these boxes in front of the characters when I wanna see a fight. Has anyone found out why this happens or how to get rid of this issue?

Having the same problem and turning on hitboxes also fixes it, quite odd!

Found something: whenever you open up the game with the .cmd file that comes with version 5.0, it shows hundreds of these errors whenever the game lags during replays which is very strange and since I'm not a coder I have no experience with game debugging, so I have no idea what this means or why it is happening. When I turn off hitboxes, it shows thousands of these errors which leads me to believe that the stuttering has something to do with this.
