I have problems when I run GTK apps, because they like ugly. Here is an example:

I used the same Desktop in other computer and they look fine.

How could I solve that?

  • KDE Plasma 5.18 has moved things about a bit.

    If a GTK application doesn't look proper, please open System Settings > Application Style and then, near the bottom, click on Configure GNOME/GTK Application Style .... In the window that opens, choose a suitable GTK2/GTK3 theme but preferably not Raleigh. You'll see an approximate preview of your choice as well.
