KeePass inconsistent styling in KDE Plasma Wayland

Brief Summary

When using a custom font (I have dyslexia so I use a dyslexic friendly font) and a custom mouse cursor (High contrast as it helps with my vision), KeePassXC resorts to using the default mouse cursor and the default font that is used for all QT apps. While this is passable, this messes with the look and feel. Even black icons are used for some parts of the app which makes buttons' icons unlegible.

Meanwhile, Qt apps that style properly are supposed to look like the image below.

Steps to Reproduce

1. Use Breeze in KDE Plasma
2. Set Colours in KDE Plasma
3. Set Fonts in KDE Plasma
4. Use Breeze Automatic icon theme in KDE Plasma
5. Use KDE Plasma Wayland
6. Open KeePassXC

Expected Versus Actual Behavior

Expected:
Since the style is Platform Native, I expect the app to respect my font and cursor preferences.

Actual:
KeePassXC uses odd styling.

That looks like you have keepassxc set to "classic" theme and you have qt5ct installed and taking over your "platform theme".

Either set KeePassXC to our dark theme or properly configure qt5ct with your style preferences or force use of the native qt Linux theming.

Also, KeePassXC prefers to run on X11 so that might also be confounding things with your font selection. You may need to either force KeePassXC to run on Wayland or setup your fonts and such for X11 apps.

Yay linux!

Hello!
I have the Classic theme, that is true.
I do not have QT5CT. I checked whether the environment variable that forces qt5ct was on and it wasnt.

┌─[soham@wwind:~]
└─╼ echo $QT_QPA_PLATFORMTHEME

┌─[soham@wwind:~]
└─╼ 

How do I force KeePassXC to run on Wayland? My fonts work fine enough for X11 apps, and I can use it in X11 apps like Vesktop

[phoerious]

Start it with QT_QPA_PLATFORM=wayland.

[WinnerWind]

I started it with that environment variable like this:
QT_QPA_PLATFORM=wayland keepassxc

The following messages were receieved

QFont::fromString: Invalid description 'GohuFont uni14 Nerd Font,13,-1,5,400,0,0,0,0,0,0,0,0,0,0,1'

qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

(The font description is valid and works in other apps)

But the fonts and icons issue still stays.

Some simple steps to try:

1. Rebuild your font config:

rm -rf ~/.cache/fontconfig
fc-cache -fv

2. Ensure there are NO typos in the font name

Linux font settings are notoriously difficult to get right across the board because they are defined in a couple places depending on application type.

Regarding the icons, those are coming from the classic Qt theme and you will need something like qt5ct to correct them. They are NOT part of KeePassXC.

[WinnerWind]

I rebuilt my font config and restarted KeePassXC (note, without logout, if that's relevant)

I don't think there's a typo in the font name as KDE Settings tells me that the font is named GohuFont uni14 Nerd Font, which is consistent with the output.

Issue is still not resolved, unfortunately.

As for the icons, I might get qt5ct/qt6ct and try to remedy it that way.

[phoerious]

Are your other Qt apps using Qt6 by any chance? That might explain the differences.

[WinnerWind]

I think that I am using Qt6, but I am unsure how to check.

[silverhook]

I think that I am using Qt6, but I am unsure how to check.

If you are using KDE Plasma 6, it most definitely uses Qt6. (Plasma 5 used Qt5.)

[WinnerWind]

I'm on KDE Plasma 6, yes.

[phoerious]

Then that's the reason. Try to configure Qt5 via qt5ct if you can't get it right via systemsettings.

[WinnerWind]

I used qt5ct to set up a really basic color theme and font combination and it worked. My cursor is still wrong but I think I can fix that with some extra tinkering. Now it won't respect my KDE desktop's color scheme but that's probably because QT5CT is over-riding it.

Should I leave this thread open until KeePassXC is fully compatible with KDE Plasma 6 or should I close it?

[phoerious]

No reason to keep it open. We couldn't do anything about it anyway.
