Xorg's framebuffer flickering on Embedded mode with Nvidia

[MCPO-Spartan-117]

This likely is a Nvidia driver issue more than gamescope's problem.

Gamescope Version 3.11.48.r11.g2791466 Nvidia Version 520.56.06 Monitor Resolution 3440x1440 Distro Gentoo/Artix

Running embedded with native resolution causes Xorg's framebuffer to flicker across 50%+ of the screen, however lowering Xorg's resolution down to the monitor's next step and starting gamescope without -W and -H (having only one of them works fine for some reason) gamescope works fine and you can raise Xorg's resolution back up to native. Killing Xorg and restarting it after gamescope might work too.

#599 might be related.

Running Vkcube, probably the worst i've seen it lmao, you can barely see it middle-right of the screen.
