Singlestat double vision in

Support Singlestat Panel
#1

Hi, I am getting following problem with the Singlestat panel from time to time:
image

If I refresh the dashboard, the values are shown normally again, until I open the dashboard after some time, then its double vision again.

Grafana version: 6.3.5
OS: Docker in Ubuntu 18.04
Database: InfluxDB 1.7.14

Is it a Grafana problem, or are some plugins not getting along together?

Thanks!

Found the problem (it is in both Singlestat and Singlestat Math - plugins): if you increase the font size >=50% and have anything but the low line_ in the postfix (even the space) it produces the same bug.
