I confirm:

• [x] that I haven't found an existing compatibility report for this game.
• [x] that I have checked whether there are updates for my system available.

Symptoms

I have two displays:

1. UHD with 140% scaling
2. FHD with 100% scaling

When I launch Split Fiction my mouse doesn't get captured and moves over to the secondary display, when I get too close to the edge of the screen.
This happens regardless of whether I select full-screen, borderless window or windowed mode.

A workaround I found is using these startup options, but they block the Steam overlay:

gamescope -f -W 3840 -H 2160 --force-grab-cursor -- %command%

Reproduction

Start the game and move the mouse to the edge of the screen, where the secondary display is placed
