Large graphs and Chrome80

I have a graph that displays 7 Influx data sets with quite high resolution in the influxdb (approximately 1-2 minutes per plot) in a ‘last 24h’ graph. The graph plots fine in Android Chrome and IE, however in Windows Chrome 80 the graph stops plotting part way through. If I reduce the ‘Group by’ Time then progressively more data is plotted until I reduce the time to 10m where all the data is shown.

I can work round the problem by manually setting a time group but this would need to change if I open out the time frame to say 3 months, and why does it only do it in Windows Chrome. Can’t be sure but I thing this is a recent problem. Upgrading Grafana 5 to 6 didn’t change anything so I’m guessing its a browser limitation.
