Reported Issues with Intel CPU & Iris Xe Graphics

Several LightningChart .NET users have reported us experiencing technical issues with rendering when using Intel® Xe Graphics. Particularly, when the default Rendering Engine is used (which is based on DirectX 11), the chart could produce unexpected results and in some cases, crash.

It is worth mentioning that other applications, for instance, gaming applications using DirectX 11, have also been reported to experience similar problems.

Currently, the information available indicates that this is a problem from Intel’s end and the Iris Xe Graphics drivers.

In the meanwhile, we have contacted Intel® and asked them to resolve the issue as quickly as possible. However, LightningChart .NET users are strongly encouraged to choose one of the three different workarounds available:

Solutions

First: install a separate dedicated graphics card, if possible.

Second: try updating the graphics driver directly from the computer manufacturer’s page or from Intel’s drivers’ page.

Third: set LightningChart .NET to use different than default drivers (or Rendering Engine). It would be done by setting Chart.ChartRenderOptions.DeviceType (in WindowsForms RenderOptions) for the SoftwareOnlyD11 or the HardwareOnlyD9 option.

Please note, the newest LightningChart .NET features (like Volume rendering and SamplDataBlockSeries) are not implemented for the HardwareOnlyD9 device type.
