Main menu has visual and audio stutters as well as periodic tearing lines.

Just to confirm, if you are playing on the default branch this stuttering does not happen? Do you have any overlays such as the AMD Radeon overlay for your graphics card? Those are known to cause issues like this.

I think I’ve solved it, by updating graphics drivers. However, the part where if the game crashes (not just the save, but the game) the computer freezes has not been fixed.
