Hi Lance,

We don't have any of the problematic video boards here - the controls were tested primary on the Intel based video boards and some ATI models and we have had very little complaints about the hardware accelerated rendering most of which were fixed after the latest video board drivers are installed (which leads us to think that those issues are caused by the particular OpenGL implementation). We're going to perform tests this week on the Radeon R9 series of video boards and will let you know if we find issues with ATI drivers.

Thanks for the feedback.  I doubt you'll have issues with the Radeon R9 series because this issue did not occur on the Radeon system that I tested.  So far this issue has occurred on every GeForce system that I've tested (GTX 760, GTX 970, and GTX 980M), all of which were running Windows 10 x64 and had updated drivers.  As I reported, I also have an issue on a system with Intel HD Graphics 4000 and Windows 7 x64.

Is there any way for you to test on a GeForce system?

Hi Lance,

We tested on an older Nvidia GeForce (650 Ti) and everything worked OK... we'll also will try to find one of the boards you experience problems with...

Thanks for the update and for testing it with a GeForce.

Did you try my sample code with a DPI setting of 125%?  You might have to resize the form (which resizes the chart) in order to notice the clipping of legend text.  I’m using Windows 10 x64, but I'm not sure if that matters.
