Adding no_display to MangoHud.conf or pressing rshift + F12 results in a black screen, instead of only hiding the MangoHud overlay.

System info:

• RX 6800 XT
• Ryzen 7 5700X
• Mesa 24.1.3 drivers from Arch repos
• Arch Linux
• Mangohud latest Git (stable has same issue)
• Gamescope latest Git

Adding the no_display option to the Mangohud configuration, or pressing rshift + F12 while using Gamescope with the --mangoapp flag results in a black screen, instead of only hiding the Mangohud overlay.

Gamescope log file:
gamescope.log

The only line that is added after hiding Mangohud with rshift + F12 is:
[gamescope] [Debug] xwm: Rejecting WM_CHANGE_STATE to ICONIC for window 0x600007

I tested this with gamescope --mangoapp vkcube.

This is reproducible for me with all combinations of Gamescope master/3.14.24 and MangoHud master/0.7.2. Test environment: Ubuntu 24.04, Ryzen 5 5600, RX 6700, mesa 24.1.4 from kisak-ppa. Same debug message.
