to summarize, i do not have Vulkan support, so i need to use OpenGL and Mangohud doesn't like running with it, giving the error ERROR: ld.so: object '/usr/$LIB/mangohud/libMangoHud.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
I checked online for a solution, which was to add export LD_PRELOAD=/usr/lib/mangohud/libMangoHud.so:/usr/lib32/mangohud/libMangoHud.so to ~.bash_profile and i also added it directly to /etc/profile since it had priority.
After logging out and back in, EVERYTHING has a mangohud instance running, and that causes KDE's taskbar and desktop to crash, but other functions somehow work.
Now of course i can remove the commad from /etc/profile and ~/.bash_profile but i also want Mangohud to work when i call for it in the terminal.
Can anybody give a better solution? I turned off Global Enable for Mangohud through GOverlay, but nothing.
Running Arch Linux 6.2 on linux-zen kernel, KDE Plasma 5.27 on Wayland

What happens if you put mangohud in your DE?

In mine, I put mangohud right near the end, and it applies to all steam games, even ones I don't specicifically tell to use it.

#

everyhting related to the DE (desktop environment) has its own Mangohud window

#

the taskbar, desktop, system settings app, most other system apps too

#

funny thing is, i tried NFS:MW (2005) and mangohud didn't work there

what file is this again?

#

that's in my /usr/share/wayland-sessions/sway

#

So you may have to add env MANGODUN=1 into it

#

assuming you don't have env vars already set

#

still nothing

#

it did not work, remember this is OpenGL we talking about

#

not Vulkan

#

the ironic thing is, if i add the command to ~/.bash_profile mangohud works in everything EXCEPT FOR WINE APPS

#

which means literally nothing has been achived
