Failure to open libpangoft2 causes crash on SDL_VIDEODRIVER=wayland

[atomicf32]

Due to the current update of cs2 dropping mouse inputs for me in xwayland I have opted to edit the cs2.sh file and make it run in wayland natively. After the edit, the game would randomly crash when opening the buy menu. After some investigation I was getting this error when the crash would occur in the shell:

wp_linux_drm_syncobj_surface_v1#63: error 3: Missing buffer
ERROR: Wayland display connection closed by server (fatal)
zenity: symbol lookup error: /lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: pango_font_family_get_face

After closer look there seemed to be two libraries failing to load in when the game boots up: libpangoft2 and renderdoc. I looked in the .local/share/Steam/steamapps/common/Counter-Strike Global Offensive/game/bin/linuxsteamrt64/ directory for libpangoft2-1.0.so as it was named in the logs. I only found libpangoft2-1.0.so.0. I tried copying the file to libpangoft2-1.0.so and the library load error went away. The crashes have not happened since. There are new errors that are appearing: Pango-CRITICAL **: 17:19:11.365: pango_layout_line_get_x_ranges: assertion 'start_index <= end_index' failed. I believe these are in place of the zenity: symbol lookup error: /lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: pango_font_family_get_face which at least does something with the buffer the font was meant to go into so that the graphics stack doesn't explode.

I would appreciate it if this issue was fixed so that others may also run the game natively in wayland.

Thanks,
Russell Hynes

Hello @atomicf32,

Unfortunately I don't think there is anything here that clearly indicates an issue with CS2. I would suggest investigating the cause for your wayland compositor crash directly. Depending on your system configuration you may be saving core dumps that should be reported upstream (coredumpctl).

[atomicf32]

After a couple days of no crashes I finally crashed again. I was able to see that I am saving coredumps. Is there any particular tool I should use to inspect these?

[TTimo]

That's very dependent on your distribution and system setup. In a developer friendly environment coredumpctl debug <id> should be enable to get a backtrace. You may have a variety of things that are crashing, the compositor may be the most upstream thing that would need figuring out.

Here is my output from backtrace full in gdb:

Could librendersystemvulkan.so be related to my compositor?

[TTimo]

I would assume this is simply CS2's fatal error after your wayland compositor has given up, assuming you are still seeing wp_linux_drm_syncobj_surface_v1#63: error 3: Missing buffer and ERROR: Wayland display connection closed by server (fatal).

You haven't provided any information on your distribution and environment. We recommend KDE Plasma and the kwin compositor. If you are looking for a good distribution for gaming, EndeavourOS may be a good pick. There's always Ubuntu of course.

[atomicf32]

I am running Hyprland. Is this a known problematic compositor?

[TTimo]

Yes, there are several issues with Hyprland. We do not recommend it.

I had the same issue, and in addition to libpangoit complained about not being able to load librenderdoc.so. I'm on fedora42, using sway, running flatpak steam. I installed renderdoc and copied the lib to the game folder and haven't seen a crash since. I'm not sure why these missing libraries would lead to cs2 crashing though, but it seemed to have helped.

anything in this coredump or is it leading to the same thing
