One thing I would like to clarify. When I subscribe on ChartMessage, than I don't get exception about rendering engine, application does not crash.

Re: Lightning chart application crash, when connected to app via RDP

When I set property ChartRenderingOptions.DeviceType = SoftwareOnlyD11, I don't get error with engine. Before there was always Hardware11. Most probably, using RDP there is no HW rendering possibility.
