Starting (AFAICT) yesterday, the "Download PNG Image" feature is broken on many of my charts.

They should look like this: 

But are being exported like this:

I put some effort in trying to figure out what was causing the issue, and this seems to affect many types of charts, but only on older Highcharts releases (<10).

Here is a minimum reproduction: https://jsfiddle.net/a3tedpu1/1/

Hi @paulo-raca,

Thanks for reporting this issue. It seems that the problematic option here is borderRadius, which produces unexpected results even in a live chart. Since this issue isn't related to exporting, please feel free to report it on the Highcharts repository.
