Unhandled error on frame drawing causing engine reinitialization

[Hacke]

We are currently developing new software for our customers that uses LightningChart and until now we had no problems during development and on several PCs in our company.

However, when we installed the software on a OptiPlex Small Form Factor 7010 (the model we sell to our customers) to test it, this error appeared:

Arction.Wpf.Charting.ChartException
HResult=0x80131500
Message = Something caused the rendering engine to reinitialize.: Unhandled error on frame drawing causing engine reinitialization: HRESULT: [0x80004005], Module: [Unknown], ApiCode: [Unknown/Unknown], Message: Unspecified error

This exception was originally thrown at this call stack:
[External Code]

Inner Exception:
SharpDXException: HRESULT: [0x80004005], Module: [Unknown], ApiCode: [Unknown/Unknown], Message: Unspecified error

After it occured I updated the Nuget packge to the newest stable version 10.5.1.1 but the errror is still the same.

Is there anything that I can do to fix this error?

This is most likely graphic drivers problem. You can test/verify that by forcing LightningChart to use different DeviceType (that is different graphic drivers). To do that you should set
chart.(Chart)RenderOptions.DeviceType property to HardwareOnlyD11 (default from 'Auto'), HardwareOnlyD9 or SoftwareOnlyD11. In addition, chart.(Chart)RenderOptions.GPUPreference property allows to switch to different graphic hardware, if such is available.

It would be clear indication of graphic drivers problem, if you see difference between HardwareOnlyD11 and SoftwareOnlyD11. Rendering difference between HardwareOnlyD11 and HardwareOnlyD9 could be explained by other factors, but it is also very like drivers, if it is computer specific.

Unfortunately we are seeing a lot of reports lately about Intel integrated graphic problems. Some of them have been described for 11th-12th Gen. CPU (https://lightningchart.com/news/intel-1 ... rkarounds/ ). To my knowledge that should be fixed with latest drivers. However, we now starting to see new kind of issues with 13th Gen on Intel CPU graphics.

If you have such 'problematic' hardware, LightningChart will allow to circumvent with different DeviceType. However, I would would suggest to submit report to Intel about this bug to facilitate resolution (report could be submitted through 'Intel Graphics Command Center' application)?
