The "Program is unresponsive" message seems to be pretty quick to trigger!

[YusS FIN]

Just little feedback on the 21.1 version.
Launching TF2 I get a "program unresponsive" message without even pressing a button!
From the days I used W10 half a year ago, it didn't do it until about 15 seconds of unresponsiveness from a game like TF2. But because some other games I've played when I used W10 and now on Linux Mint have gone unresponsive and the message hasn't appeared, it is definitely an improvement!

Just a note about unresponsive games: Some games seem to take Fullscreen mode as taking over the entire screen and any control the user has (example game just so you can try it out: Space Engineers. Install many mods for it too). That means you can't access programs on the taskbar/panel and Super key can't open the menu. So if that message appears, it is the easiest way to defeat the game. Especially for someone like me who doesn't yet know all the tricks you can do on Linux!
