Deadlock icon doesn't show up on panel in KDE on Linux under Proton for some reason

[chexo4]

See above. It's the icon on the far right. Here's what information I can find about my software versions:

Bazzite 43 (Universal Blue image-based distro based on Fedora packages)
KDE Plasma 6.6.4
KDE Frameworks 6.25.0
Qt 6.10.3

Linux Kernel 6.17.7-ba29.fc43.x86_64 (64-bit)
Wayland display server

Let me know if there's anything else y'all (well, in the Deadlock team) would like me to dig up to help troubleshoot this.
