Thunar icons are messed up

[bran.damon]

Hi,

I installed XFCE from packages on a FreeBSD VirtualBox guest OS, on a Windows host. It is the latest version: FreeBSD my-freebsd 12.2-RELEASE FreeBSD 12.2-RELEASE r366954 GENERIC amd64

When I open the Thunar file manager, I see that some icons look messed up, like the Home and Refresh icons, see the attached image.

Does anyone know how to fix this?

Thanks,

Bran
