Just wanted to share a fix for GTK Flatpak’s looking terrible on Manjaro (font not antialiased, correct size, cursor wrong etc.)
If you install Flatseal from flathub it will display the issue on vanilla Manjaro.
The issue is fixed if xdg-desktop-portal-gtk package from the official repo’s (extra) is installed (and the computer rebooted). Visually it is night and day.
I was wondering if the package could be installed with Manjaro as default given Manjaro’s support for flatpaks. This would greatly improve the flatpak experience on Manjaro.
