LinearGradientBrush on some W10 devices problem

Hello,

I would like to ask whether there is anyone else who ran into similar issue as we did during migration of our W8 application to W10. Out of several other issues that we ran to this one remains to be a complete mystery to me.

A closer description of my problem can be found here:

But the basic concept is that application with simple grid that has LinearGradientBrush set as background shows black background no matter what I do with it. This problem however is present only on some devices like one Lenovo ThinkPad Tablet 2 that we are using for testing purposes.

Any ideas what the actual problem might be?

Thank you very much.
