Hello @duckster, swrast is mesa's slower software renderer and the fact that Steam is trying to use it tells us that you're using the nVidia proprietary driver, but don't have 32 bit userspace driver support installed. The nVidia proprietary driver requires that the running kernel module, 32 bit userspace, and 64 bit userspace versions have the same version to work properly.
nVidia's CUDA driver PPA is known not to provide 32 bit userspace support and that issue is being tracked at #5778. You might be able to to workaround the issue by installing a newer nVidia driver than what is bundled with the CUDA packages from https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa/ and install all the CUDA components you need you need without the meta-package(s) that explicitly ask for the version bundled with CUDA.
After that, then Flatpak has a chance to match up to the more widely used driver version inside their container system.
Closing as a duplicate of #5778.
Nothing extracted yet.
