Problems with custom visual viewport refreshing

[vodinn]

Hello, we have created a custom visual using online developer tool. When out visual is in developer tool and we resize viewport it is updated correctly, but not in production mode. After we have imported our visual to online service and we resize viewport it looks like viewport is not cleared on resize. When we resize window our chart is rendered in the new position but we can still see its copy in previous position. Can anybody advise how to fix this?

Hey, the rendering is controlled by your custom visual. The problem is most likely within the custom visual itself.
