Describe the bug

This issue happens only on Android and with skia renderer.
When the app comes from foreground mode an strange "shadow" is applied over the chart, probably because the chart is duplicated one above the other.

To Reproduce

1. Create an line skia chart
2. Go foreground mode after it rendered first time
3. Go back to the app

Expected behavior
Don't duplicate the chart

One solution that we got is use the svg renderer on android.
