Display problem after switching to GNOME3 from unity in Ubuntu 16.04

Question

So I switched my desktop environment from Unity to GNOME3 in Ubuntu 16.04. I tried using both display managers (lightdm default in Unity, gdm3 as gnome recommendation). However my display seems to be broken. I am attaching a screenshot for clarification

Answer 1

The problem is associated with gtk-theme you're using, not with display manager. That theme is incompatible. I suggest using other theme.

To switch to default Adwaita theme, which should work always in GNOME, use this command

gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita'
