Perspective PowerChart Display Issue

I'm seeing an issue with the Power Chart in Ignition 8.3 Perspective. When adding a tag to the trend, the trend begins "flickering" and is nearly unusable. It seems like maybe some kind of delay with polling trend data?

In the attached video I am using a pre-made page with a Power Chart component that comes with the Kanoa Ops module, however I see the same thing on other gateways by creating a new view and dropping a Power Chart onto it.

I see this behavior in 8.3.3 and 8.3.6. I do not see this behavior in 8.1.22.

In the video I am using a tag from a Core Historian, but I see the same behavior using a SQL Server backed historian.

Any ideas on what could be causing this behavior?
