last night everything is okay but from today after everything looks odd. Also vlc black theme changed to white one I don’t know what’s happening. Really need help…to fix this issue

Most likely this is not the cause of your issue, but it should be fixed asap.
A garuda-update normally does the trick.

How can i fix this ? any hint

Execute garuda-update from terminal…
For the theming, I’m afraid you’ll have to wait for a GNOME helper. Maybe check Settings > Appearance

The issue is the way we were theming Qt apps on Gnome was with the QGnomePlatform project, which is sadly no longer being maintained: GitHub - FedoraQt/QGnomePlatform: QPlatformTheme for a better Qt application inclusion in GNOME

The packages have already been removed from the Arch repos. They are still in the AUR, and if you install them that way it would be an easy fix for your issue:

paru -S qgnomeplatform-qt5-git qgnomeplatform-qt6-git

However, installing unmaintained packages from the AUR is not recommended and it is not likely to be something that will work in the long term unless development of the project resumes.

Moving forward–or at least for now–we are going to switch to using Kvantum to theme Qt apps on Gnome. It has some limitations, but Gnome doesn’t have a lot of options anymore and Kvantum seems like it’s better than nothing.

If you don’t have it installed yet, you can pull it down with Pacman:

sudo pacman -S kvantum

Kvantum has a bunch of built-in themes you can use, or you can install this one which is meant to match the Libadwaita style (it’s reasonably close): GitHub - GabePoel/KvLibadwaita: Libadwaita style theme for Kvantum. Based on Colloid-kde.

You will have to set a few environment variables to get Kvantum theming to work:

sudo micro /etc/profile.d/

# If it's a Wayland session, set some environment variables.

if [ "$XDG_SESSION_TYPE" = "wayland" ]; then
	export QT_QPA_PLATFORM=wayland

# Set some other environment variables

export QT_STYLE_OVERRIDE=kvantum

Save and exit, then make the script executable:

sudo chmod +x /etc/profile.d/

Log out, log back in, and you should be good to go setting up Kvantum. Run kvantummanager from the command line to launch the application to get your new theme set up. Run it with sudo to configure a theme for root applications if you’d like.

Some of the root applications need their .desktop files modified to launch from the menu if you are running Wayland, by the way. You may have noticed that if you tried to launch one of them (it doesn’t do anything). There are some changes coming down soon to fix that, but in the meanwhile you can edit the .desktop file yourself if you want to to get them working (it’s just one line per file):

sudo micro /usr/share/applications/garuda-boot-options.desktop

Change the Exec= line to this:

Exec=/usr/lib/garuda/pkexec-gui garuda-boot-options

You can do the same thing to fix Garuda Network Assistant if you wish.

pkexec-gui won’t use the Kvantum theme by default unfortunately. There is a change in the works to fix that, but until it comes down you’d have to add the change manually if you want root apps to honor your theme when you launch them with pkexec-gui.

sudo micro /usr/lib/garuda/pkexec-gui

# Elevate
if [[ $EUID -ne 0 ]]; then
    exec pkexec /usr/lib/garuda/pkexec-gui "$@"
    exit 1

# Restore some variables from parent process
while IFS= read -rd '' var; do export "$var"; done < <(grep --null-data -ae "^\(XDG_CURRENT_DESKTOP\|WAYLAND_DISPLAY\|XDG_RUNTIME_DIR\|XDG_SESSION_TYPE\|XCURSOR_SIZE\|LC_.*\|LANG\|LANGUAGE\|QT_WAYLAND_FORCE_DPI\|QT_STYLE_OVERRIDE\|\)=.*\$" /proc/$PPID/environ)
if [[ -v WAYLAND_DISPLAY ]]; then
export XDG_RUNTIME_DIR="/run/user/0"
exec "$@"

This may be more hacking around than you bargained for, but like I mentioned a lot of changes have come down so Gnome is basically a work in progress at the moment. Also, Gnome 45 is coming out soon and who knows what will happen then. More big changes are planned, so no sense reinventing the wheel for now.

I would say just set up a Kvantum theme you can live with for now (let us know if you find a good one) and probably we’ll take a closer look at Gnome after the dust settles following the 45 release.
