the game is 32bit, is there a separate mangohud package for 32bit in flatpak?

[zastrixarundell]

Most likely there isn't, at least I can't find it.

Hm, all of these issue (mosty not having gamescope) are really making think of moving to Bazzite instead of Kinoite.

I'll switch on my laptop and then check if the issue still persists.

[zastrixarundell]

Well after messing around, this game neither oblivion wanted to start out of the box and I don't have the will to see to debug it. I'll see to make an issue on repo for MangoHud fltatpak to setup 32bit dependencies.

[zastrixarundell]

Hm, I've actually started Fallout: New Vegas which is supposedly 32bit and MangoHud is working there, so it might be an issue with it being 32bit then?

What proton version are you using for Prince of persia? I had to use 3.7-8 for it to start at all

[zastrixarundell]

Proton-GE 9.2, flatpak version of Steam as it didn't load some files on the native version but worked out of the box on flatpak.

@zastrixarundell On latest proton you're using the new steam-runtime and I think Valve has changed some paths inside the runtime that's been causing some trouble lately. Just to check if that might be the issue, could you please try this launch parameter:

MANGOHUD=1 LD_PRELOAD='/run/parent/usr/lib/extensions/vulkan/MangoHud/$LIB/libMangoHud_dlsym.so:/run/parent/usr/lib/extensions/vulkan/MangoHud/$LIB/libMangoHud_opengl.so' %command%

Edit: or this one:

MANGOHUD=1 LD_PRELOAD='/run/parent/usr/lib/extensions/vulkan/MangoHud/$LIB/libMangoHud.so:/run/parent/usr/lib/extensions/vulkan/MangoHud/$LIB/libMangoHud_dlsym.so:/run/parent/usr/lib/extensions/vulkan/MangoHud/$LIB/libMangoHud_opengl.so' %command%

[zastrixarundell]

Both of them gave a similar display issue:

Although for the first set of options made the lines static, the other one made the lines intrerlace.
