Tray module stopped working with Hyprland v 0.55.*

[Jules3182]

Issue:

Essentially what the title says, after updating hyprland to version 0.55 my waybar tray module stopped working. Unfortunately I didn't notice for a bit, so I am not sure exactly which version of hyprland or waybar broke it, but it was working properly before 0.55. I also ended up building waybar from source to fix a known issue with workspaces, but the tray still doesn't work. The other modules in the bar still work as expected with the same configs, and after the update broke the workspaces bar I am suspecting something similar happened with the tray module as well.

I tried some troubleshooting to try and figure out the issue but ended up stumped. I haven't seen any discussion about it online yet so figured I should report the issue. Below is as much relevant information as I could think of to provide, please let me know if you need more.

Update:

Build was compiled without all of the proper dependencies. After double checking installed dependencies and rebuilding it is now working properly! Lesson learned, gonna double check dependencies from now on and do one thing at time to better narrow down blame for issues that may arise.
