OBS doesn't work in ML4W

[2ve]

I installed OBS earlier when I did the archinstall. I got installed Hyprland and ML4W. OBS couldn't launch in ML4W. I tried to reinstall OBS, but it said error: failed to prepare transaction (could not satisfy dependencies) :: removing obs-studio breaks dependency 'obs-studio' required by wlrobs-hg. I already got installed wlrobs-hg. I didn't know why it wasn't working.
I had to type flatpak install flathub com.obsproject.studio. I launched OBS and it worked. I added the screen capture (pipewire). OBS didn't have a display option. It only has the open selector.
I can't fix OBS Studio in ML4W. I wanna test it out.

Thanks for testing. I am using OBS for all my videos. What's your distro and how have you installed OBS Studio?

[2ve]

My distro is ArchLinux.
I installed OBS Studio on other desktop environment.

Can you run sudo pacman -S obs-studio and try again?

[2ve]

I ran sudo pacman -S obs-studio. I went to the app launcher, but I couldn't open OBS.

[2ve]

I mean, no.

Ah. Can you run flatpak list and check if obs-studio is listed there?

First, try this in a terminal:

QT_QPA_PLATFORM=xcb obs

If it works, make it permanent:

cp /usr/share/applications/com.obsproject.Studio.desktop ~/.local/share/applications/

Then edit ~/.local/share/applications/com.obsproject.Studio.desktop and change the Exec= line to:

Exec=env QT_QPA_PLATFORM=xcb obs

This forces OBS to use X11 (XWayland) instead of native Wayland, which avoids the crash.

(don't remenber why exactly but maybe the "remove background plugin" was in cause)
