I asked for help on every forum I know,but no one could help me.
My problem is that no LD_PRELOAD Env Var I tried works.
I use kde so I report it here.
My .bash_profile looks like this:
```
#
# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc

export LD_PRELOAD=/usr/lib/libMangoHud.so:/usr/lib32/libMangoHud.so
export MANGOHUD_DLSYM=1
export MANGOHUD=1
export CLUTTER_BACKEND=wayland
export GTK_USE_PORTAL=1
```
Every normal Env Var works but the LD_PRELOAD ones don't work.
I tried it with many other programs.
Do I have to put my env vars elsewhere?
I use arch wayland.
