Hello
I have Lenovo Legion laptop with RTX3070 Ti, running under Linux Mint OS.
Laptop screen resolution is 2K 165 Hz, but I generally use external 4K 60Hz monitor, so playing CS2GO on it wasn't smooth enough. I decided to decrease screen resolution from 4K to Full HD, and after doing that the game is broken: it can load and show start screen, and I see mouse pointer running across the screen, bit it doesn't respond to clicks! cannot start game, cannot even go to settings and change screen resolution back to 4K
not really sure if it's a problem of Steam or the game itself. Please advise! I've got suggestion from Steam support to put this here in GitHub.

Steps for reproducing this issue:

• run the game on 4K resolution
• decrease resolution to Full HD
• re-run the game

Thank you!

Clicking (and mouse input in general -- that includes hovering) is also broken on Arch Linux, MATE, picom, X11, scaled down from 2560x1440 to 1920x1080.

I can open the console, join a game (map de_dust2) and in-game, I can shoot, but Panorama doesn't accept mouse inputs at all (neither does the console).

One workaround to at least be able to click would be to set the resolution manually using the CLI parameters: -w 3840 -h 2160.

EDIT: Actually, it looks like the mouse cursor is stuck in the middle of the screen, because opening the buy menu and clicking buys me whatever item I have under the crosshair. Input works properly in the Steam overlay.

yes, the mouse is stuck in the middle when running with sub-native resolution in full screen, this occured both on x11 and wayland, I also have this issue.

A temporary solution for me was to actually size down the resolution of my monitor directly through settings.

@Tunahan-Uysal could you please advise where can I find the settings to decrease the resolution? I have made full re-install of a game, but the problem still exists. Thank you!

Yes, whether you're using a Mac, Gnome or KDE they're available in your settings, in the Monitor section. Just search up settings and lower it to your preference and if your game is improperly set up with incorrect resolutions you can modify the starting params for CS2 through the three dots on steam, config, and add -h yourheighthere -w yourwidthhere
If you're using Gamemode, or any other program alongside CS, just add the params right of %command%
