How can i fix app icon "showing as a 3d cube logo"

I have some applications that don’t show the app logo in the toolbar, like the ProtonMail app. It just shows a cube (the one in the Qubes app menu not the Qubes OS logo) instead of the ProtonMail logo. I don’t know how I can fix this.

Thx ! :slight_smile:

Do you use KDE plasma in dom0/sys-gui?

I am on Qubes 4.2.3
I never change the default desktop environment so i am on xfce .

Oh ok, my mistake then. I have the same issue but assumed it was KDE specific

Some programs work and some do not, doesn’t matter if they’re .deb/.rpm, flatpak, or appimage.

Strangely the icons appeared properly one time, never to be seen again. Makes me suspect this could be easily fixed.
