Tray Icon not themed after update to version 2.6.2

[mifidord85]

Overview

After upgrading from version 2.5.4 to 2.6.2 the tray icon in my xfce-panel no longer uses my system theme (in this case Papirus) but just falls back on the icons in the hicolor folder. In the changelog for version 2.6.0 I can see that a lot happened regarding icons and theming (especially relevant is #4161 I think). My issue is only with the tray icon, everything else looks perfect. So when I downgrade again to version 2.5.4 the tray icon is using my system theme again.

Context

I am not quite sure if this is intended or if it is a bug, so my question is, is it possible to just have the tray icons use the system theme? I understand the decision to use one single theme inside the application, but the tray icon should be themeable in my opinion.

Duplicate #5130. This is an unfortunate bug in theming and possibly qt. We did not intend to allow any external changes to the tray icon styling. With that said, I would be open to an option to allow system icon on Linux. @phoerious

Working as intended. You see our app icon, not some random hicolor one.
