GtkSpinner doesn't spin in VMs
@segfault3
Submitted by segfault3 Link to original bug (#768289)
Description
When run in a VM, the GtkSpinner is standing still and doesn't spin. This was tested with Debian Stable (GTK 3.14), Debian Sid, and Fedora (both GTK 3.20.6). The GtkSpinner, which is displayed when adding a new printer in the GNOME Printers application, was used as an example. It does spin when run on bare metal, but not in a VM (tested with VirtualBox and KVM).
Version: 3.20.x
