So for a while now Ive been having the issue of broken QT Apps running on gnome when not a flatpak. This would cause the applications to be mostly white and unusable, so i finally went about figuring a way to fix it. If you have this issue try this. I couldnt get qgnomeplatform to work with this and had to swap to kvantum.
1.First you need to uninstall
sudo pacman -R qgnomeplatform-qt5 qgnomeplatform-qt6
2.Then install kvantum
sudo pacman -Syu kvantum
- set the QT style override either in /etc/environment for global or ~/.bashrc for per user by adding this line
3.5 You can do this per app with adding this to the launch options
This fixed kdenlive which had become almost completely broken for me and also weird theme issues in OBS-Studio.
One thing to consider is that kvantum won’t theme qml applications while qgnomeplatform does.
You may just be trading one problem for another.
Well in my case with qgnomeplatform the only functional QT application i had was obs-studio but it had some really bizarre theme issues. This was the only thing that fixed it for me outside of being forced to use flatpaks for anything QT.
EDIT: now that i think about it i believe it began with the introduction of libadwaita
Edit2: This was similar to my issue except everything but the 2 video previews and a couple buttons was white when using qgnomeplatofm
you can stil use qt5ct and adwaita, and select adwaita-qt and install that style also from repo
Installed Gnome and Budgie yesterday and this is exactly what I’m looking for XD
