Sketchbook Pro does work on this device, but there are known limitations due to the hardware configuration.

Rotate Canvas may not be natively supported on this device.

When launching Sketchbook Pro on this device, Sketchbook may display a warning message: “The video driver may not be installed correctly, canvas rotate is not supported” 

Once dismissed, Sketchbook Pro will launch.

The message will appear each time the app is launched unless you go into Sketchbook Pro Preferences and disable the Rotate Canvas feature.

If you have installed the Microsoft OpenCL, Open GL and Vulcan Compatibility Pack on your Surface Pro X, these drivers will allow rotate canvas in Sketchbook Pro, but causes graphic artifacts when the main window is maximized. This can be avoided by disabling rotate canvas or ensuring the main window is not maximized.
