Pre-req:

• Apply latest changes from end of last week contained: quay.io/rh-ee-emurasak/monitoring-plugin:pf6-3
• from Peter's repo dotfiles/stowed/xonsh/xontrib/yaml/cluster-monitoring, in order to unmanage CMO and scale down pods to enable CMO deployment be changed

oc patch clusterversion version --type json -p "$(cat disable-monitoring.yaml)" 

kubectl scale --replicas=0 -n openshift-monitoring deployment/cluster-monitoring-operator 

kubectl scale --replicas=0 -n openshift-monitoring deployment/monitoring-plugin

• Manually change CMO Deployment - YAML in this line https://github.com/openshift/cluster-monitoring-operator/blob/5d1fd1bb52eeb9b2f877c45de0cf93e2f9fffb95/manifests/0000_50_cluster-monitoring-operator_05-deployment.yaml#L76
• Save
• Reload (probably will ask to reload again)
• Scale up CMO deployment pods and monitoring-plugin

kubectl scale --replicas=2 -n openshift-monitoring deployment/cluster-monitoring-operator

kubectl scale --replicas=2 -n openshift-monitoring deployment/monitoring-plugin 

• Go To Observe > Dashboards
• Take a look at the legends

Actual Result: 

There is a shadow / gradient on the legends that doesn't seem to be ok for Dark mode. Should be adjusted.
