Incorrect auto theme when starting minimized

[SinnySupernova]

Overview

Auto theme doesn't respect dark system theme when KeePassXC is started with "Minimize window at application startup" enabled

Steps to Reproduce

1. Enable "Minimize window at application startup" in Settings -> General
2. Relaunch KeePassXC and open the UI by clicking the tray icon

Expected Behavior

Auto theme inherits dark system theme

Actual Behavior

Auto theme is light

Context

Everything works as expected when "Minimize window at application startup" is disabled

KeePassXC - Version 2.7.9 Revision: 8f6dd13

Qt 5.15.14 Debugging mode is disabled.

Operating system: Artix Linux (Arch based) CPU architecture: x86_64 Kernel: linux 6.9.5-zen1-1-zen Desktop Env: KDE Plasma 6 Windowing System: Wayland

I can't replicate this

I tried to record a video of it. And it's even weirder - it's inconsistent. Sometimes it works and applies the dark theme, sometimes it does not.

Edit: Moreover, it does not seem to depend on the setting being enabled

Is there any way I could gather and provide more information?

This is most certainly related in some way to your desktop environment and/or theme and/or wayland. You might be running keepassxc in X11 through xwayland which could certainly mess with stuff.

It was indeed running through XWayland. After installing qt5-wayland (which doesn't seem to be in optional dependencies of the keepassxc package) KeePassXC is running in Wayland native mode.

But the theme issue is still happening all the same, unfortunately I couldn't figure out any pattern yet. When I repeatedly close/reopen the program without changing any settings, the theme that's set is seemingly random.

The program seems to apply the correct application theme every time after a restart, however if I log out and log in (same user), the tray menu icons theme is wrong and the app theme is correct:

In this scenario, when not minimized on start, KeePassXC seems to first set the light app theme, then changes it to dark shortly, but the tray icons don't reflect that change.

@phoerious may need a periodic check for linux

[phoerious]

Rather than doing that we should check for the org.freedesktop.appearance.color-scheme DBus interface. I don't know whether all desktops implement this yet, but that'd be the way to go.
