That sounds like a strange graphics glitch! The cloaked characters and laser-like effects could be caused by outdated graphics drivers, incompatible settings, or a problem with the game's shaders or texture files. I'd try updating the graphics drivers, resetting the graphics settings, and temporarily disabling any mods to see if the issue disappears. If it continues, sharing a screenshot along with your graphics card and game version could help others identify the cause. For a fun gaming break, check out Geometry Dash.
