Description of problem:
See provided photo.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Login to Gnome classics session
2.Suspend the laptop (Search for suspend in gnome-shell)
3.Wake up the computer from sleep
The top panel on lock screen is white
The top panel on lock screen should be black
I don't think there's any need to suspend. Login to gnome-classic, lock screen, start to unlock screen, see it's the wrong colour. I've observed this behaviour with gnome-shell-3.26.2-5.el7.x86_64 on CentOS 7 CR.
I am not able to reproduce with gnome-shell-3.28.2-1.el7.x86_64, so it is fixed by rebase
