[SOLVED] Buggy KDE Desktop Theme

I'm using KDE with Breeze Dark Theme with the "Default" GTK Theme and this is the result.

If I use Artix-dark for the GTK Theme it's not noticeable, but it seems there are parts of the GTK theme that are being used for the plasma desktop.

Just changing the 'Global Theme' may be not enough, perhaps you need to also change it in 'Application Style' tab. See this post too for more.
You should also read our wiki entry to get some insight on the subject.

When I do that the GTK applications theme switches to Breeze and there are still White bars with Black/Grey font.

Can't Artix copy off Manjaro Linux or KDE neon's solution to this? I don't have this problem on those distros.

This is how the Breeze Dark Theme looks like in Artix:


This is how Manjaro looks like with Breeze Dark Theme and Default GTK Application Style :


Artix takes some parts of the GTK Application Style and Mixes it with the Global Theme.
While Manjaro has isolated KDE and GTK Application Style, so I can have two different themes for GTK and KDE apps.
Can't the same be done with Artix? I'm not that tech savvy so I don't know the differences between Atix and Manjaro.
Except the init systems.

Bonjour,

Just yesterday I installed Artix Linux XFCE OpenRC from the artix-xfce-openrc-20210426-x86_64.iso using Calamares.

I don't use Thunar, but Dolphin.

When choosing the Adwaita theme, I notice that the visual themes are mixed.
The background of Dolphin, Gimp, or some configuration windows is black...

I found an absolutely unscientific method to fix it (but it has been working for over a year):

Reinstall all the packages present.
sudo pacman -S $(pacman -Qnq)

After this "cure", all the colors are correct everywhere ... on condition of commenting (add # at the beginning of the line) in / etc / environment the two lines:
# QT_QPA_PLATFORMTHEME=gtk2
# QT_STYLE_OVERRIDE=gtk

sudo mousepad /etc/environment

P.S.
Personally, I change the background color of Dolphin:
edit ~/.config/kdeglobals and modify
[Colors:View]
BackgroundNormal=220,220,220

mousepad ~/.config/kdeglobals

Can't try right now. The latest 4 updates did something to my runit system (I think) and now firefox, telegram and pamac won't start, and pacman -Syyu returns error: no usable package repositories configured.
I don't know what happened.

What does cat /etc/pacman.d/mirrorlist say?

I don't think there's any problem there.
It says Generated on 2021-04-26 and Mirror list of Europe, North America and Asia Servers.

I get error when starting apps that says error while loading shared libraries: /usr/lib/libatspi.so.0: file too short
It links to libatspi.so.0.0.1 which is a zero byte file.

I am not an expert.
Have you installed packages from AUR or locally unsupported packages?

I leave the rest to the specialists ...

No, I just updated some packages. My PC crashed later so maybe that's the reason.
I'll just reinstall. This was a new install anyway.

Probably.
Especially if installation processes were in progress.
No, it didn't happen during the update idk
I commented out:
# QT_QPA_PLATFORMTHEME=gtk2
# QT_STYLE_OVERRIDE=gtk
in  /etc/environment and now the theme works as it should!
But now I noticed another problem.
The cursor animation constantly changes between the default and breeze.

Delete libatspi.so.0.0.1 and re-install at-spi2-core. No need to re-install the entire system.

This is mentioned in the last paragraph of the wiki entry I linked in my previous post:
Our Gtk-based DEs use the QT_QPA_PLATFORMTHEME and QT_STYLE_OVERRIDE environment variables to control the appearance of Qt applications. Using an all-toolkit theme like Breeze or Artix-dark is recommended and no additional actions are needed to achieve visually appealing results. Otherwise, those variables may need to be disabled in /etc/environment. For some Qt applications that follow ~/.config/kdeglobals, you may need to delete the lines containing 'artix-dark' from it (or delete it).

I have this laptop that crashes often, so after I fixed it, it crashed again and at-spi2-core got corrupted again, but this time I already installed timeshift from AUR and had a btrfs snapshot ready.
Timeshift should have a package in the main repositories, because there are cases when I try to install a package from AUR like pamac-tray-icon-plasma where I get a compile error.
I can live without pamac-tray-icon-plasma but not without timeshift.
I used pamac-tray-appindicator but it seems it's not in the repositories anymore.
