obs-vkcapture does not work with 32 bit games

[QuickFastly]

Describe the bug

I just did a fresh install of bazzite, so everything should be as default as it gets. The only package I've layered is mullvad-vpn. I set up my Steam library using the preinstalled native Steam, and moved my old Bottles (flatpak) games into new Lutris (native) prefixes, then installed OBS, the VK capture plugin, and the flatpak vulkan layer through the terminal. I did NOT install OBS from the first boot portal, so if that does anything special, that might be my whole problem.

After adding obs-gamecapture %command% into the launch options of a couple of my games, nothing seemed to be working.

After pulling my hair out over it and troubleshooting for several hours, including testing with both vkcube and glxgears (both captured fine), I realized that apart from one game, everything I was testing was very old, so I tried loading a more recent game, and it captured fine.

I also tested installing Bottles as a flatpak and running one of my old games through that instead. It captured properly. Out of curiosity, I rebased to testing just to see if there's been an update that fixes whatever's going on here, but nothing changed.

That made me think that for some reason, I didn't have the 32 bit version of the native vkcapture package installed, but rpm -qa | grep obs returns the following:

obs-vkcapture-common-0.0.git.354.aa3c43a0-1.fc41.noarch
obs-vkcapture-vulkan-layer-common-0.0.git.354.aa3c43a0-1.fc41.x86_64
libobs_vkcapture-0.0.git.354.aa3c43a0-1.fc41.x86_64
libobs_glcapture-0.0.git.354.aa3c43a0-1.fc41.x86_64
libobs_vkcapture-0.0.git.354.aa3c43a0-1.fc41.i686
libobs_glcapture-0.0.git.354.aa3c43a0-1.fc41.i686

The 64 bit files are in /usr/lib64 and what I assume to be the 32 bit files are in /usr/lib

So, in short:

• OBS installed as flatpak, including necessary flatpak plugin and vulkan layer
• 64 bit games running through native Steam or native Lutris capture as expected
• 32 bit games running through native Steam or native Lutris do NOT capture
• 32 bit games running through flatpak Bottles DO still capture
• For whatever reason, the 32 bit version of native vkcapture is not being loaded by flatpak OBS

What did you expect to happen?

I expect to be able to enter obs-gamecapture %command% in the launch options of any game and have capture functionality working, regardless of whether the game is 64 or 32 bit, and regardless of vulkan or opengl.
