it looks like pressing tab sometimes gets the cursor stuck in a weird state where its technically not free moving but still acts like it is and when it hovers over an invisible tab ui element you cant shoot
this only happens to me in sandbox, fix this plssss, still not fixed, basically can't shoot sometimes and the testing tool light up as if we're tab+hover the testing tool
would like to report this bug happening for me too. in a match or sandbox. i cannot use keyboard for 5-10 seconds after pressing Scoreboard keybind. the actual Key is not the factor here its the Scoreboard being used.
added: its like pressing tab puts your keyboard in other screen or program. just like actual alt+tab would. pressing mouse buttons brings you back
