This happened to me after waking from suspend, so that might have something to do with it. It looks like the exact same issue, black window and UI in top-left corner.
This also happens to me when the PC is idling for a longer period of time (for example overnight) with locked screen.
Same over here on Fedora 37. They only show up after sitting idle overnight so far. Other logs and screenshot attached to #9806
Edit: I'm also using a KVM to switch to my work machine which effectively disconnects both displays--I see some errors related to that in the logs
Edit2: Not sure if related, but I tried to close the windows and steamwebhelper crashed then it brought down Cinnamon with it

This also happens to me if I leave steam running overnight.
I have had this happen as well, though it doesn't seem to happen on KDE, just Gnome and GTK-based desktops. hopefully that helps.
Unfortunately I'm on KDE so we've got all bases covered I guess. :-D
All menu windows become visible if steam started with no monitor

I can confirm this also still happening to me on Steam version 1690583737 on a system running Fedora 38 with KDE Plasma and Wayland, and using an AMD Radeon 6700 XT. It only happens if I turn off my two monitors with Steam running overnight and usually makes me have to kill Steam in the System Monitor because it doesn't respond.
@CptCookies12 The menu windows still work. It will exit the the Exit Steam menu button, or from the taskbar icon.
I'm not sure it's related but have a feeling it is.
While my (1) displayport monitor is powered off and I (2) try connecting to the same Linux machine via Steamlink app on my Android phone, Steam crashes.

I am also having exactly the same issue. With the steam installed through flatpak I don´t have this issue but with the package installed from pacman I do.
Oddly, I haven't had this happen in a few days. Anyone else experiencing that as well? Nothing's really changed on my end except for maybe a few updates.

I've not had this issue or the VRAM leak issue since the latest update. I think they fixed it.

Same here, around 13 days uptime and no issues anymore so I think it's fixed.
I have not noticed it happening lately and I just tried it again: started Steam, turned off montior, waited a few seconds, turned monitor back on, no glitch.

Closing per the last couple comments.
I'm having this issue on Windows, has been happening the last few days. Commenting here so it isn't closed as duplicate.
Hello @Sn0uu, please use Steam Support to report issues you're seeing with the Steam client for Windows.
I'm having this issue on Windows, has been happening the last few days. Commenting here so it isn't closed as duplicate.
Same here! It's getting real annoying.
Just chiming in that I observed this (for the first time) just now on Windows 10, so it's still happening on some platforms.
In case it offers a clue:
To all the Windows users commenting on a bug you're encountering:
May not be 100% related, but this exact bug/issue with the same symptoms happens if the SDL_VIDEO_DRIVER (used by SDL3) environment variable is set to wayland. In this case, it doesn't even require the steam client to be left to idle for a while; It happens as soon as steam starts. Removing the environment variable or setting it to x11 instantly fixes the issue.
Another quirk of this bug is that the mouse is misaligned on the main steam window (i.e., it's not clicking where my mouse actually is; there's an offset). I assume this is because the main window now has my system GNOME title bar attached to it.
Also, some parts of the UI are just completely broken. For example, I can't click on some games under my list of games on the left in my library screen.
Tried opting into steam client beta - didn't fix/change anything.

(again, tried this on non-beta and I had the same issue).
[Edit: figured out the cause of this issue and changed my comment to reflect such]
This happens to me and I'm on Windows. I know this is for Steam Linux but it's the only thread I could find about the issue, so I'm hoping that help narrowing down the causes.
Steam Version: 1709846872
It happens when I lock my Windows session or when I log into another local Windows user on my PC for a while and then re-open the Windows user session I didn't log out of.
I have this issue too. Running Wayland on Kubuntu with a KVM switch. When I switch to the other system for more than a couple hours, I get 12 windows, one for each menu.
Wife has the same issue Garuda linux, dual monitor setup, Wayland, no auto logout. I also run Garuda, no problem, single monitor, power settings to always on and no auto logout.
I have been having this issue for a while now. On EndeavorOS KDE/Plasma 6 Wayland (and previously with KDE Plasma 5 X11) with an AMD RX6700XT graphics card.
I use a KVM to switch between this computer and another though Ive had it happen even when I didn't switch and just let the screen look and monitors standby by themselves.
I've also seen it in as little as a few hours all the way to not happening for a few days.
Same issue, very similar setup to DeviceLimit (NVidia 4090 GPU, but exact same OS/desktop environment). Problem began after I started using Wayland.
