BUG: Non-sidebar "Application Preferences" window content is unreadable with dark colour scheme.

[RokeJulianLockhart]

Describe the bug

The preference window displays with incorrect (and ureadable, in my case) colouration. I presume that it is hard-coded.

How To Reproduce the bug

1. #!/usr/bin/env sh
   lookandfeeltool --apply 'org.kde.breezedark.desktop'
   	# [SE AskUbuntu](https://askubuntu.com/revisions/1183309/2#:~:text=lookandfeeltool%20%2D%2Dlist%20to%20get%20a,change%20to%20your%20desired%20theme.)

   Note, relevantly, the undermentioned (theme) overrides that I have set:

   1. #!/usr/bin/env sh
      flatpak override --show

   2. [Context]
      filesystems=xdg-config/gtk-3.0:ro;xdg-config/gtkrc-2.0:ro;xdg-config/gtk-4.0:ro;xdg-config/gtkrc:ro;

   However, this is standard for anyone utilizing anything except Adwaita (which basically means anyone not using GNOME).

2. #!/usr/bin/env sh
   flatpak install 'https://dl.flathub.org/repo/appstream/io.seamly.seamly2d.flatpakref'
   flatpak update  'app/io.seamly.seamly2d/x86_64/stable' --commit=2a9e282ff33761c34a85245e2d4572949cc4263be0b491d25c2268fb57d43545
   flatpak run     'app/io.seamly.seamly2d/x86_64/stable'

3. Select the entry labelled "File" in the toolbar.

4. Select the entry labelled "Application Preferences..." in the context menu.

What should have happened

It should render with the same colouration as the rest of the GUI.

No, dark mode is simply not supported at the moment. I already tried workarounds, but our Qt base version (Qt 5.15) does not support it properly and our styling in the application as well...

And its fine to report the bugs here as we also publish the flatpak version, so keep all the bugs here in one place

Same effect happens on Mac, by the way

Thanks for reacting that fast. I was just reporting some other bug, when I saw this, and commented. I'm on Mac Book Pro running Sequoia 15.2, but this issue is existing quite a while, not new. And it's not only the preference menu – the whole coloring scheme is not usable in dark mode. I am usually disabling dark mode temporarily to be able to work with Seamly2D.

By the way: Some dialogues haven't enough space...

On the active draft block, black lines stay black, nearly invisible on the dark background. The inactive part(s) are ok, though.

Correct... as it's already been pointed out Seamly does not support dark mode.

Thank you for pointing that out. In the future it would be more helpful if you create a seperate issue. That being said, Seamly also does not handle increasing the screen scale by more than 125% which may be the issue.
