Description

@legions-developer

Hey creator of EvilCharts here... while creating charts i found issue in v3 ( i'm attaching video of same chart, same code but in different versions from v2.15.4 -> v.3.6.0

What is the current behavior?

The bar chart below flickers and appears to be double-rendered when hovered over. I’m using custom bars with shape props. ( This was in v3.6.0 recharts )

What is the expected behavior?

Now here is example with recharts v2.15.4 (note: it have same code, same chart) but here you can see chart works smoothly?

Please provide a demo of the problem in a sandbox

Provided the videos above, as well as made a demo source code public... can be used to reproduce issue

Which versions of Recharts, and which browser / OS are affected by this issue? Did this work in previous versions of Recharts?

I suspect this issue is in version 3 of Recharts itself. However, I’m trying to downgrade version 3 to see if a specific version is causing the problem.
