Seems like the ability to incorporate icons from the system's theme is either broken or the icons being requested are not part of any of the active icon themes.
When you look at QPrompt's top menu bar and left menus, do you see any icons or no icons at all? (Icons from the editor toolbar don't count, those always ship with QPrompt.)

Thank you! All icons are missing. I will look into this.

Quick update: QPrompt is reading system icons correctly, but installing the missing icons doesn't solve this issue because changes to the system theme's icons are not being reflected inside of QPrompt. I don't know if this is a problem with AppImage containerization, a problem with the Gnome desktop environment, or a problem with KDE's icons framework. The first two seem more likely.

Because your setups are usually single purpose, I will suggest installing a distribution with a desktop environment based on the Qt toolkit, such as LXQt and KDE Plasma; both usually come with breeze-icons pre-installed, which is the icons set used by QPrompt. Debian 11 is one of such distributions, all you must do is select KDE Plasma Desktop instead of Gnome Desktop Environment during installation. Also, both Plasma and LXQt offer better performance than Gnome.

I intend to respect system icon preferences on Linux distributions, but not fully if it means QPrompt's most essential icons will go missing. What I will do is replace the most essential icons with copies that are to be included within QPrompt.

Was using Debian 11.3's LXQt, switched to KDE... icons are back, thank you.

[Cuperino]

Interesting... I will look into LXQt, maybe I'm wrong about them using the same icon set... Maybe they use different icons in Debian LXQt than Lubuntu 22.04, or maybe there lies a clue into why icons aren't working.

[Cuperino]

Forced use of internal copy of the breeze-icons used for QPrompt's main actions: toggle, increase, reduce. All other icons will continue to be missing on distros that do not provide them, but at least the two icons used for these 3 actions will show. This way system icon themes can continue to be respected.

I did not force the inclusion of all themes because the approach I use on Windows and macOS fails on Linux, and the alternate approach being used here automatically limits our ability to dynamically pick different icons based on factors like screen resolution and up-scaling.

Closing issue for now.
