Your system information

  • Steam client version (build number or date): 1709846872, Wed, Mar 6 21:28 UTC -08:00
  • Distribution (e.g. Ubuntu): Slackware64-15.0 (What else?™ :nerd_face: :wink:), GNOME 46
  • Opted into Steam client beta?: No
  • Have you checked for system updates?: Yes
  • Steam Logs: steam-logs.tar.gz
  • GPU: Nvidia (NVIDIA GeForce GTX 1660 Ti, driver version 550.76)

Please describe your issue in as much detail as possible:

At some point during the last weeks, my Steam client suddenly started using the old, ugly X11 default icons instead of the system-wide configured default ones from Adwaita.

Screenshot from 2024-04-04 05-43-06 Screenshot from 2024-04-04 05-43-28 Screenshot from 2024-04-04 05-44-13

Slackware does not ship GNOME, so on my system it's all self-compiled and installed into /usr/local via GNU stow. In particular, the Adwaita icon set is located in /usr/local/share/icons/Adwaita, and the cursors are located in the cursors subfolder of that, ie. /usr/local/share/icons/Adwaita/cursors. My $XDG_DATA_DIRS is set accordingly:

[zlatko@disclosure:~]$ echo $XDG_DATA_DIRS
/home/zlatko/.local/share/flatpak/exports/share:/usr/local/var/lib/flatpak/exports/share:/usr/local/share:/usr/share

After a lot of head-scratching, I decided to use strace to see what's going on, and this showed that some Steam (sub)processes do look into /usr/local/share/icons/Adwaita/cursors and are able to access it, some also do look there, but turn up empty handed for some reason (-1 ENOENT), and some don't even bother to look there, and only look into /usr/share/icons/Adwaita, /run/host/user-share/icons/Adwaita and /run/host/share/icons/Adwaita instead. I have no idea where /run/host comes from, this directory does not exist on my system.

Of the two processes that do actually follow $XDG_DATA_DIRS, only one of them manages to actually read the files, the other one, for some reason I cannot quite understand (chroot? sandbox? bwrap?), gets -1 ENOENT (No such file or directory) for the very same files that the other process can read just fine.

All other (sub)processes are only looking in places which are bound to fail.

[zlatko@disclosure:~]$ grep -l Adwaita steam-strace.* | xargs grep -L /usr/local/share/icons/Adwaita | xargs grep -ho '/.*Adwaita' | sort | uniq
/proc/3772/fd/20", "/usr/local/stow/adwaita-icon-theme-45.0-@GNOME3/share/icons/Adwaita
/run/host/share/icons/Adwaita
/run/host/user-share/icons/Adwaita
/usr/share/icons/Adwaita

Here's a tarball containing the full strace logs, just in case that helps to figure out what's going on: steam-strace.tar.gz NOTE: this is actually a .tar.xz, but GitHub won't allow me to upload that. However, when compressing with gzip, the tarball is 28MB, and GitHub only allows 25MB for uploads. :roll_eyes: So I compressed it with xz (version 5.2.5, so no worries about backdoors :wink:) and renamed it to .gz.

What does not fix the problem:

  • installing the Adwaita directory directly to /usr/local/share/icons (instead of having it symlinked there by stow)
  • creating a symlink from one of the actually searched directories (ie. cd ~/.icons; ln -s /usr/local/share/icons/Adwaita/ . or cd /usr/share/icons; ln -s /usr/local/share/icons/Adwaita/ .)
  • creating symlinks of the cursor contents from one of the actually searched directories (ie. mkdir ~/.icons/Adwaita/cursors; cd ~/.icons/Adwaita/cursors; ln -s /usr/local/share/icons/Adwaita/cursors/* . or mkdir /usr/share/icons/Adwaita/cursors; cd /usr/share/icons/Adwaita/cursors; ln -s /usr/local/share/icons/Adwaita/cursors*/ .)

What does actually fix the problem:

  • physically copying the complete Adwaita folder to either ~/.icons/Adwaita or /usr/share/icons/Adwaita, ie. cp -av /usr/local/share/icons/Adwaita ~/.icons/. or cp -av /usr/local/share/icons/Adwaita /usr/share/icons/.
  • doing a bind mount of /usr/local/share/icons/Adwaita at /home/zlatko/.local/share/icons/Adwaita, ie. having a line like /usr/local/share/icons/Adwaita /home/zlatko/.local/share/icons/Adwaita none bind,ro 1 0 in /etc/fstab

Sooo ... what's up with that? Why can't I have my system icon & cursor theme in /usr/local anymore, all of a sudden? :thinking: :man_shrugging:

Steps for reproducing this issue:

  1. Have your system icon theme physically located in /usr/local (or anywhere else, other than ~/.icons and /usr/share/icons, for that matter).
  2. Be a good citizen and set your $XDG_DATA_DIRS accordingly.
  3. Start steam.
  4. Enjoy steam proudly showing X11's cursor icons from the late 1980s, instead of your configured modern icon theme. :scream_cat:

If there's anything else you need to know about my system or setup, just let me know. Thanks for listening! :+1: :slightly_smiling_face:

EDIT 2024-06-28: added second workaround
