When I helped another user this week to install White Sur, I really liked the appearance of the theme and tried to install it on my LinuxMint XFCE computer.
But the theme was really strange, not like on gnome, and messed up my panel completely.
I downloaded the gtk and icon theme from github. There was said it is for all gtk desktops. Then I installed the themes with the installer scripts. On gnome everything went fine yesterday, but in xfce it doesn't look right, as if it doesn't fit in.
Is it neccessary to download the themes from xfce look or isn't White sur suitable?
You could try it with downloading from WhiteSur Gtk Theme - Gnome-look.org and then extract it and control if a xfwm Folder is included. then put it on the themes Folder and try how it looks.
If it looks the same, that should be all what You could get for xfce. You have to think about that xfce isn't Gnome. So it looks different and isn't the same.
