Mouse not screen locked to primary monitor

Regardless of whether I use native, fullscreen, windowed, or enable the "full screen focus behavior" setting, my mouse is never locked to my primary screen. During normal gameplay it's not an issue because the cursor is not being used, but when in menus or if I alt+click, my cursor can leave my primary monitor off to either of my 2nd or 3d monitors. This is frustrating because a misclick on one of those monitors tabs me out of the game. I've tried using -fullscreen or -full in launch options, disabling fso, running as admin, and none of it made a difference. I'm on Win11 and have a relatively recent PC (i7-13700k, 3070) so I don't think this is a compatibility issue. The easiest workaround I've found is win+P and switching to primary monitor mode, but this disables my other monitors until I switch back.
The behavior I expect of a fullscreen program is to mouselock my cursor to the monitor its on until I alt+tab and minimize the game.
 
I'm having the same issue. Started happening randomly today. It's extremely annoying. Need an option to lock the mouse to the screen like in Dota 2.
It's also happening for me in a match. It's unplayable
 
anybody got a solution to this mouse problem?

I have a work around for the time being as it appears it's a windows 11 issue as other games are having the same issue. for example Kingdom Come Deliverence which now that i think about it could be a Nvidia thing. Anyway the fix is this Youtube video.


You will need to dowload some software to lock the cursor to your screen.
I have downloaded the software and ran Kingdom Come Deliverence and locked the mouse and it seems to be working.

thank you. it works
 
Same issue here and my housemate has also started experiencing this. I am using Dual Monitor Tools and full screen to solve this for the moment but would really like to go back to windowed mode soon.

Yeah agreed, hopefully the devs find out what's causing it. Because to download a 3rd party tool to fix this issues is less than ideal.
 
Same issue here, had a similar problem with Dota 2 and never found a way to solve it, maybe it's a Source 2 thing
Started happening since today's update
