Grafana Graphs are Flickering on Postgres Data Source #67247


  • What Grafana version and what operating system are you using?
  • Grafana version: V9.2.6
  • Data source type & version: Postgres Data Source
  • OS Grafana is installed on: Using Helm Charts installation on Kubernetes
  • User OS & Browser: Chrome, Mac OS, (M1)
  • Grafana plugins:

What happened:

I am exploring the Grafana and installed its open source application using its helm charts repo. However, I encountered some UI issues during the exploration and my testing. I implemented a PoC project where I consume time series data constantly and visualize it on my dashboards. I used the Postgres Data Source to feed my graphs, but soon later I realized that Graphs are flickering. This especially happens when you switch the wifi network and test it on the slower network. In the case of slower network, Graphs are jumping right to left during the rendering phase.

What you expected to happen:

I expected to be smooth visualization no matter how fast and slow the network is. I was expecting graphs to not flicker and pass network. testing. Maybe, not render at all, but rendering with flickering causes bad experience.

How to reproduce it (as minimally and precisely as possible):

It is hard to reproduce quickly, even for me, but the reproduce step would be having dashboards ready and then switching to slow network during the time series data consumption. This should cause to flickering.
