Mangohud only shows up in Native Linux Unity OpenGL Games in native desktop resolution

[nebadon2025]

If i run a Unity3d native opengl game with mangohud and my desktop resolution is 1920x1080 and the game is also running in 1920x1080 everything works fine. If i change the game resolution to 1280x720 mangohud disappears, even if game is restarted and will come back when game resolution is set to match whatever you have your desktop resolution set to. I have tested this with "The Falconeer" and "Aragami"

Play with oGL "workarounds", see if helps.

i have same problem #641 (comment)
originally i thought it was a problem with art of rally, but i noticed when i tried crumble that mangohud was visible when i started the game and it was running desktop resolution, but as soon as i lowered res, it disappeared.
im guessing this affects any native linux game and for non native linux games it just reports wrong (desktop) resolution.

I tried these out and none of them made any difference.

Not trying to bump an issue with no extra new information but I can indeed confirm this is happening on my machine too with slime rancher. However as a workaround if you need mangohud and a lower resolution gamescope will still show mangohud even at different resolutions if you use both.

INTEL_DEBUG=norbc MANGOHUD=1 MANGOHUD_DLSYM=1 ENABLE_VKBASALT=1 gamescope -h 720 -H 1080 -- mangohud ./SlimeRancher.x86_64

(Ignore INTEL_DEBUG that is for my intel gpu)

@Vixeliz set gl_bind_framebuffer=0
