Implementing IChartCustomDrawer sometimes results in blurry text

Go to the next issue (open or closed)
Go to the next open issue

When drawing text in the upper-left corner of the chart, after several ticks the text becomes blurry almost as if it's being rendered on top of itself.
When a bar closes or you scroll the chart left/right, the initial draw is clear again, but blurs after several ticks.
The same does NOT occur if I render the exact same text in the exact same manner in the upper-right corner of the chart.

Steps to reproduce this issue

Implement IChartCustomDrawer and use it by calling ChartCustomDraw.Register()
In the Draw() method when phase == EDrawPhases.Final
Draw text using context.graphics.DrawString()

Additionally changing the following preference makes no difference:

File -> Preferences -> "Improve visual appearance of drawing tools..."
