The snapstore gui has no background

Hi,

I just upgraded to Ubuntu 20.04 and tried to load the Snap Store app.
I was greeted with that:

The app has no background. Others apps are not affected.

It works for me on Ubuntu 20.04. Perhaps there’s an incompatibility with the graphics driver, I really don’t know. When running it from the command line:

$ snap-store

Do you you see different error messages that might give a hint?

Turns out that the theme I was using from ubuntu 18.04 seems not to be compatible with Snap Store.

Step to reproduce:

  1. Install numix-gtk-theme from ppa:numix/ppa
  2. In Gnome Tweak Tool, choose Numix as the Applications theme in the Appearance page
  3. Launch Snap Store : theme is not loaded

Workaround:

  1. Choose Yura in Gnome Tweak Tool
  2. Snap store is correctly displayed
