[PC] Major visual glitching in Virus Tag online

So i was playing the new virus tag mode great fun but i wish we had access to these maps(layouts) in single player shouldn’t be hard to add in surely? if its in the game it will just be enabling it heres hoping for a patch.
Anyway i alt tabbed out of the game when i went back onto the window i was experiencing this:
Youtube (sorry if im embedding that wrong)

its quite off putting and distracting the only way to get rid of it is to close the game and restart

anybody else getting this?
