Please describe your issue in as much detail as possible:

I'm using SteamOS 2.0 (based on Debian 8). I'd blocked Steam updates before it dropped old distros (in 31th July 2025).

It's wonderful. I cat run modern Chromium on an old system using your Steam Soldier (bubblewrap + Pressure Vessel).

My configuration:
CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz
GPU: Intel HD 4000 (Ivybridge Mobile)
NVIDIA GeForce 650M (Discrette)

Linux 4.11.12, X-Server 1.20.7, libdrm 2.4.97, Mesa 19.0.8, NVIDIA 440.100.

Previously I can start Steam on Intel GPU. When I can start a game on NVIDIA GPU using these commands: __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia %command%

Now Steam runs only on discrette GPU.

__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia steam

I don'ask you for fix Steam on old Mesa, it's too late. I ask you about the reason of the problem. Do I need to upgrade Mesa or set some environment variable?

I'll not offend you if you close the issue with "won't fix". Maybe somethere else is another issue with same bug that contains the fix?

Steps for reproducing this issue:

1. Start Steam on integrated GPU
2. See errors in terminal.
