Linux Build Doesn't Capture Mouse

[TheCircularK]

In the Linux flatpak build courtesy of Shiion and SirMangler, the mouse is not captured by the game window. This is true for full screen, windowed, and borderless window.

Fedora 40

Kernel 6.10.6
Reproduced on 6.10.3, 6.10.4, and 6.10.5.

I have reproduced this issue with one, two and three monitors active. The distance between the mouse pointer and the in-game pointer decreases with fewer monitors.

If there's any other info I can provide, please let me know.
