Frozen screen in PC...

Well this has been a really annoying problem.
When I am playing Era while I am chating on Discord at the same time and I change tabs from Era to Discord and then come back to Era they screen is frozen and I can't move. They only solution is to make it fullscreen with the fullscreen at the top right part but if in Era there is a profile opened or menus opened it's totally frozen so I have to relog. Fix that :/

Interesting, Possibly a anti-hack thing? If its a one-time thing then i guess graal doesnt like the switch
