Research direction
Start by reproducing Steam startup and collecting the dmesg entries shown in the report, then determine whether the sigaltstack overflow is caused by Proton or an external component such as the NVIDIA driver. No source file or test is named, so done would require identifying the responsible subsystem and confirming the overflow no longer occurs.
