Pie chart legend display regression after upgrade

I have 2 Linux boxes running Grafana (w/ Influx). After upgrading one of them to Grafana 6.3.3 + Pie Chart 1.3.8, the legend text on the pie (well donut in my case) is no longer visible (its majority goes to the actual donut). On the second non-upgrade box/install the legend is perfectly visible. No changes have been made apart upgrading Grafana from 6.2.5 to 6.3.3 and mandatory follow-up upgrade of Pie Chart from 1.3.6 to 1.3.8. I am attaching pics showing the diff. Thanks!
