This pop-up message has been displayed at least 6 times so far. This may be due to the recent changes made to the game as the first one appeared in one of the past few days. The image displayed above is for the browser version (2016). It is unlikely that this is due to local hardware limitations. This error seems to occur when the user is browsing through the game (seeing profiles, teams, players and so on). When the pop-up appears and then the user clicks on the window, the game automatically reloads by itself.
