Hello @rehdi93, I expect that this is a side effect of the "safe browser shutdown workaround." You can try to avoid this issue by running Steam with STEAM_DISABLE_BROWSER_SHUTDOWN_WORKAROUND=1 steam from a terminal (from https://github.com/ValveSoftware/steam-for-linux/issues/9458#issuecomment-1613759526).

My understanding is that workaround is to compensate for a video driver bug and will need to stick around until the affected driver versions are uncommon.

the env variable does fix it, ty ^-^

Hello @rehdi93, I expect that this is a side effect of the "safe browser shutdown workaround." You can try to avoid this issue by running Steam with STEAM_DISABLE_BROWSER_SHUTDOWN_WORKAROUND=1 steam from a terminal (from #9458 (comment)).

What are the affected driver versions? Is it safe to disable the workaround with the Nvidia 550 driver?

Hello @Reonu, https://github.com/ValveSoftware/steam-for-linux/issues/9576#issuecomment-1989492738 looks like the relevant detail.

To update (given that previous answers assumed this would be resolved as of Nvidia's 550 drivers): I am using Nvidia's proprietary drivers, version 550.100, and I am still experiencing this on X11 (without an environment variable set).

My system information:

• OS: OpenSUSE Tumbleweed
• Steam version: 1721173382
• Output of uname -a: Linux <redacted> 6.10.4-1-default #1 SMP PREEMPT_DYNAMIC Mon Aug 12 05:49:20 UTC 2024 (0363a35) x86_64 x86_64 x86_64 GNU/Linux

after upgrading to Fedora 41, this problem no longer happens. I can run Steam w/o STEAM_DISABLE_BROWSER_SHUTDOWN_WORKAROUND

running Wayland w/ nvidia driver 560.35.03
