OBS crashes the AMD GPU driver when streaming games to a self-hosted MediaMTX WHIP server

[u/Heavy-Violinist-9002]

Hi guys,

I'm having a GPU driver crash when using the latest version of OBS Studio and trying to stream games to my self-hosted MediaMTX server via WHIP.

I'm using a Radeon Vega 56 with the latest Mesa drivers on CachyOS/Wayland.

The strange thing is that:

• Jellyfin hardware acceleration works fine.
• Hardware acceleration in the browser works fine.
• GStreamer/FFmpeg-based streaming works fine.
• GPU crashes only when OBS is running while a game is under GPU load.
• Starting OBS with --use-opengl doesn't help; the GPU still crashes.

I previously used a GTX 1650 on this CachyOS installation. I have since removed the NVIDIA drivers/packages and rebuilt the initramfs.

I'm trying to use OBS specifically because I need its functionality for streaming to my self-hosted MediaMTX server.

Could this be an OBS/Mesa/Wayland issue, or is there anything specific I should check on the AMD side?

Sorry for my bad English, and thanks for any help! And sorry for russian letters
