GTK not applying to all applications

Hello, my gtk is in some applications really ugly. how can i resolve this (Xorg with nvidia drivers)?


The theme seems not to apply to pulse audio.

What application is it that’s not working right?

Different applications:

  • Pulse Audio
  • Freeplane
  • Hexchat
  • Audacity
    Update:
    After setting the theme again in the Gonme Tweak Tool, they all applied the default theme.
