overte Using Overte with Wivrn on my laptop: segmentation fault

Hi and thanks for this great software. I'm trying to launch overte appimage using Wivrn. I'm using

wivrn official flatpak 0.22
overte official appimage 2024.11.1

Wivrn is successfully connected to the Quest 3

This is what happens on Overte side log.txt

Let me know if I can retrieve some other useful details

What GPU and driver version do you have? If Nvidia drivers, then are you using Vulkan layer described here? https://lvra.gitlab.io/docs/hardware/

It looks like segfault is caused by Opencomposite failing to start. Opencomposite fails to create Vulkan instance, so this would also be really worth reporting to Opencomposite maintainers. Here's the relevant part of the log:

I am marking this as question, since this appears to be an issue with OpenComposite. Overte itself appears to be getting terminated by OpenComposite rather than crashing.

OOVR_MESSAGE: OpenComposite Error - info in log: Vulkan Call failed, aborting. /run/build/opencomposite/DrvOpenXR/tmp_gfx/TemporaryVk.cpp:62 TemporaryVk. Error code: -9

Last time I tried OpenComposite myself, it didn't crash like this. One thing you could try is to get WiVRn through Envision rather than Flatpak: https://gitlab.com/gabmus/envision/ That way we can rule out that Flatpak is causing problems.

Ada has a temporary workaround for this. Quoting from Discord post:

the TemporaryVk crash in opencomposite is because it's trying to load a non-existent vulkan driver inside the appimage's libraries, you can work around it by extracting the appimage and modifying the LD_LIBRARY_PATH line in AppRun to also include your system /usr/lib64 directory (though with that it seems like it might also need qt5-webengine installed on your system?)

Need to do other debug, what I can say is that I tried with latest overte commits compiled with nix and there's no segmentation fault, although the video is not correctly shown in the VR device. I will give other details in the next days

I managed to run overte on meta quest 3 with wivrn, doing this

./Overte-2024.11.1-x86_64.AppImage --appimage-extract
cd squash-root
sed -i 's|LD_LIBRARY_PATH=\$curdir/usr/lib64|LD_LIBRARY_PATH=/usr/lib|' AppRun
./AppRun

Of course I have all the libraries required under /usr/lib

Amazing

I tried the above command and got this error

./overte/interface/interface: symbol lookup error: /home/kit/Downloads/Overte/squashfs-root/overte/interface/../libraries/material-networking/libmaterial-networking.so: undefined symbol: TEXTURE_META_EXTENSION

Anybody know which library I need on Arch?

I appear to be getting a similar failure when launching in VR. Launches fine in desktop mode.

I tried the fix mentioned earlier, but got this error:

[default] QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

Please try the --useExperimentalXR command line argument to use OpenXR instead. E.g.: Overte-2025.05.1-x86_64.AppImage --useExperimentalXR.
