Invisible buttons in the tray interface

[cyqsimon]

Apologies beforehand for the lacklustre information I may be providing. I'm really not sure where to even start in diagnosing this issue - nothing I did caused any change in application behaviour. Feel free to drill me for any additional information you may want.

Relevant components

• [x] Standalone tray application (based on Qt Widgets)
• [ ] Plasmoid/applet for Plasma desktop
• [ ] Dolphin integration
• [ ] Command line tool (syncthingctl)
• [ ] Integrated Syncthing instance (libsyncthing)
• [ ] Backend libraries

Environment and versions

• syncthingtray: 1.1.12, qtutilities: 6.5.2, c++utilities: 5.11.3
• Qt version: 6.2.0
• C++ compiler (name and version): gcc (GCC) 11.1.0
• C++ standard library (name and version): Sry not sure how to check this, not a C++ dev
• Operating system (name and version): Linux 5.4.150-1-MANJARO x86_64

Bug description Buttons not visible in the tray interface; see screenshot

Steps to reproduce

1. Install syncthingtray-qt6 via AUR and launch with no args
2. Left click the tray icon

Expected behavior Interface buttons visible

Screenshots

Additional context

• The buttons are there and respond to clicks; if I hover with the cursor, the tooltip also pops up. It's just they're completely invisible.
• I have tried to use alternate icons/theme/etc., via system settings, syncthingtray-qt6 CLI args, and syncthingtray GUI settings. Nothing I did had any effect.

Looks like the icon engine plugin is installed into the wrong directory for the Qt 6 version. I'll fix that. As a workaround you can use the Qt 5 version in the meantime.

This should be fixed in the latest version of the qtforkawesome-qt6 package.

Thank you! Confirmed fixed after updating qtforkawesome-qt6 and restarting syncthingtray-qt6.
