i've got my shield set as my right mouse button, i doubt that this is a mouse issue because on windows it works perfectly fine and is only doing this with the newest patch.
when i press my shield button, it seems to get stuck on my shield and the only way to desarm it is by typing in a message, this can become extremely annoying in arenas where i risk getting killed all the time.
prior to this bug, a few times while using the shield id be sent to the desktop ( i play in full screen 1280 x 720) and i almost got killed cause of it, thankfully i didn't.
anyone else have this problem?
basically this but with your shield button:
