I have several graphs in Zabbix (version 3.4) that show unsigned integer values over time. When viewed in the dashboard (as a graph widget), there are extra pixels around the lines that I can't explain.

Where are those coming from? How can I get rid of them? Is it some strange antialiasing artifact that arises from the very closely spaced measurements?
