worked fine before.after changing some settings(fps boost) like disable fullscreen optimization I cannot click on the scoreboard(idk what its called).the thing that pops that shows loadout/mute/report when right-clicking.

this is an image from a fan work.but this is the scoreboard im talking about

I can free the mouse cursor(middle mouse click) and I can see the leaderboard.but when i right/left click on something on the board I start shooting my gun.What is the problem here?How to fix it?
