Hello @PalomarLP, can you completely close Steam, then run steam from a terminal, and share a log of the terminal spew leading up to Forced create but already created for SharedObjectEvent in a gist?

Also, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

Sure :),

That terminal spew is shorter than I expected to read, perhaps the distro-provided Steam package is redirecting some of it to ~/.steam/error.log?

Dont think so ,there is no such file , there is only a text file called "bootstrap_log" in ~/.steam(logs) . In there are just entries from like 2 months ago

https://www.reddit.com/r/pop_os/comments/mgou2h/steam_black_screen_when_updating_kernel/ hints that this is a regression in Pop OS's kernel (or possibly their mesa 21.0.0 build) that went out yesterday (https://www.reddit.com/r/pop_os/comments/mgjlka/linux_511_and_mesa_210_released/).

Possible , I did an Update Today. I'm not very familiar with kernel stuff though .Is there a way to resolve this without waiting for a patch?

Although this works ?:
steam -no-browser steam://open/minigameslist

I had steam open for about half an hour now and it fixed itself???? After a restart it went back to being borked.

I'm having a similar issue on Arch Linux. The description is exactly the same, but it doesn't seem to resolve itself. This issue started happening today

I have the same issue with Fedora for the past two weeks, 5.10 and 5.11 kernels.

I am seeing a lot of this:

.local/share/Steam/ubuntu12_64/steamwebhelper.sh: line 23: 11425 Segmentation fault (core dumped) ./steamwebhelper "$@"

Fedora's Mesa update 20.3.5-2 seemed to resolve this for me.

Also seeing this issue, on Ubuntu 21.04. Here's a gist on the stdout running steam from the terminal.

https://gist.github.com/jethrokuan/b27022cd7c157abf581d7b54bfc5c6c6

The error message is a little misleading. the file exists, I guess it just doesn't run properly.

Confirmed happens (blank content view) on fedora 34/rawhide . Big picture mode works fine and games etc run. There are font rendering library missing symbol issues in the stdout and I have read previous reports indicating it is because the client is linked against an ancient version of said library that is now aging out from deprecation in most distros. Please fix.

:wave: This still appears to be a problem on Arch/6.1.12-arch1-1 to some extent.

Entering and exiting Big Picture mode seems to resolve the issue temporarily, but it appears to correlate with Steam running at the time the system is put into a suspend via systemctl suspend.

The earlier mentioned log files don't seem to exist, and nothing is written to system logs.

I experience this on Debian Bookworm. If a start steam up it's fine but if my computer goes to sleep it seems that when I go back to steam the library is blank. Other tabs, such as the store, seem to work.

I disabled GPU accelerated rendering and so far my issue seems to have gone away. It may be there's an issue with that. In my case, I'm running an Nvidia 3090TI GPU so it could be an issue between interface GPU rendering and Nvidia drivers? For the record, I'm using Debian Bookworm with driver version 525.85.12 on this system.

We'll see if it continues to work ok or not, I suppose. So far so good.

^ Disabling GPU accelerated rendering in web views also appears to have resolved this for me :crossed_fingers: Also on nVidia (4070Ti), and previously experienced this with a 2070 Super.
