Fullscreen has no cursor boundary to second monitor anymore?

i wonder if anyone else has the same bug.
i have 2 monitors and i think since patch 2.4 my ingame cursor has no boundary to the second screen anymore even tho i am playing in fullscreen mode. this now leads to me constantly moving my cursor accidentially on second screen and clicking there which makes losing the focus of my game. VERY UGLY AND ANNOYING !!

is this bug only on my side ? or does anyone know a solution for this ?

There should be an in-game option to lock the mouse to the game window.

ah yea i just saw the solution also, thanks !
they should have made it active per default.
… and not in Gameplay but in in Video Settings …

Thanks for bringing this to my attention actually, I didn’t realize Fullscreen is the new “Windowed Fullscreen” now that the cursor isn’t confined. Finally, I can use my other monitor without the game looking stupid on my main monitor.
