Hi ! I've noticed a graphical bug : When on a server in spectator mod (didn't try as a driver), the button used to switch from full screen to reduced window into the UI doesn't work anymore after a session switch. Better than words, here is a video when the problem occurs : Session is switching : Button doesn't work anymore : When it happens, the first click on the button almost works, i mean it look like the display is in full screen but it is stuck behind the UI. Game was in windowed mode. But it happen also in fullscreen mode. It it quite anoying when trying to stream league events . Have a nice evening! Nicolas
