@kisak-valve I haven't figured out how to copy this from the task manager yet. This process, by the way, is not the only one that is duplicated, they also accumulate:



A little log from the terminal.

[...]/usr/share/steam/compatibilitytools.d/proton-ge-custom/[...] is probably the key detail here. d3ddriverquery64.exe is used by Steam's shader pre-caching subcomponent to help figure out which shaders are relevant for games that use various versions of Proton and should complete its task very quickly. Since this isn't happening, then the issue is with that particular version of Proton.
Please reconfigure any games using that third party version of Proton to use a mainline Proton release, remove proton-ge-custom from the system, and test how Steam behaves without it.
If that helps, then this quirk is something that needs to be investigated in the third party compatibility tool.
Thank you. That really turned out to be the reason.
Thanks for testing. Closing as not a Steam client issue.
I've found what the problem is. The changes in Proton-GE are taken from Proton Experimental. And this problem repeated itself when specifying Proton Experimental for the same game. Exactly the same processes start piling up and Steam won't close.
https://github.com/ValveSoftware/Proton/issues/5680 is tracking the Proton Experimental variant of this issue.
@kisak-valve I installed a git version of xfce4-taskmanager to copy the full paths of those processes. I installed a git version of xfce4-taskmanager to copy the full paths of those processes. However, chunks in the middle are still cut out.

@kisak-valve I have fixed the problem. I don't know if this will work for others in the future but ask to do it just in case. In my case, removing mangohud completely helped. Installing mangohud even without running it immediately breaks wine and steam.
Then after looking at AUR repositories I saw mangohud-nonvidia, installed it and no problems. Apparently there is a conflict between vanilla version and AMD hardware.

Your system information
Please describe your issue in as much detail as possible:
When you click to close Steam, the standard Steam close window pops up, but the client does not close. The Task Manager also does not show any processes or attempts to close. The closure can only be enforced. The problem also appears in the stable version of the client. Every time the client is killed and started, a new process descendant appears, which is the very 1st one in the screenshot above, and they pile up and pile up.
Second problem: After forcibly killing the main Steam processes, many child processes are left.
Steps for reproducing this issue:
Just try to close the client.
