Created attachment 169494 [details] Video footage of the cursor bug in Counter Strike 2. SUMMARY When opening a menu in a game, the mouse isn't always reset to center, it will if the camera angle in-game doesn't change and the menu is closed and reopened. It feels inconsistent and I'm often looking for my cursor on screen. STEPS TO REPRODUCE 1. Launch a game from Steam (Proton/Native). 2. Open up a menu where the cursor normally would be centered on the screen. 3. Observe current cursor position. 4. Exit the menu. 5. Move mouse around in-game. 6. Open up the menu again. 7. Observe updated cursor position. OBSERVED RESULT The cursor changes location when bringing up the menu after moving the camera angle in-game. EXPECTED RESULT The cursor should be centered upon opening the menu after moving the camera angle in-game. SOFTWARE/OS VERSIONS Linux: OpenSUSE Tumbleweed (available in About System) KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 Kernel Version: 6.8.8.1-default (64 bit) ADDITIONAL INFORMATION Affected games: - Counter Strike 1.6 - Counter Strike 2 - Cyberpunk 2077 - Ratchet and Clank Rift Apart *This does not happen when starting KDE in a X11 session from SDDM!* *All steam games I've tried so far are affected by this* - I have tried updating to KDE unstable from openSUSE repo (KDE 6.1). - I have tried running the game in gamescope with `--force-grab-cursor` parameter. - I have tried using `QT_QPA_PLATFORM=xcb` when starting Steam. - I have tried using `QT_QPA_PLATFORM=xcb` as a launch parameter for the game. - I have tried forcing a software cursor by using `KWIN_FORCE_SW_CURSOR=1`. - I have tried using an older version of KDE in Kubuntu 24.04 LTS. - I have tried using Steam from Flatpak and openSUSE repo. - I have tired disabling and unplugging all my other monitors. - I have tried disabling the integrated GPU. - I have tried launching Steam from TTY. - I have tried setting scaling to 100%. - I have tried setting Legacy applications scaling to 'Apply scaling themselves' and 'Scaled by the system'.

UPDATE: I have tested Nobara, Fedora, openSUSE Tumbleweed, Arch and Kubuntu in the meantime. X11 and Wayland behave the same now. Gamescope, even in a TTY or when passing the `--force-grab-cursor` parameter, also behaves the same. - Counter-Strike 2 (Native/SDL_VIDEO_DRIVER=x11): Cursor gets centered in-game after an update. Steam overlay does not center cursor upon opening. - Counter-Strike 2 (Native/SDL_VIDEO_DRIVER=wayland): Breaks steam overlay - Counter-Strike 2 (Proton Experimental): Cursor in steam overlay gets centered when playing on a map. - Ratchet & Clank: Rift Apart (Proton Experimental): Cursor in steam overlay and when opening in-game map does not get centered. It does however center the cursor in the weapon wheel menu. - Cyberpunk 2077 (Proton Experimental): Cursor in steam overlay gets both centered in-game and on the start menu. Every other menu (journal, maps, inventory) in the game will randomly not get centered, but instead get placed on the left edge or right edge.

It makes Minecraft in particular pretty unplayable.
