Hardware Acceleration - Disable & Black Textures

Hello all,

For a project I’m combining Monogame with a library called XWalk.
XWalk requires hardware acceleration to show anything.
The problem is that Monogame is giving me black textures if hardware acceleration is enabled.
These black texture don’t happen every time, it seems it mainly happens at startup.
Without hardware acceleration Monogame works fine.

So I’m looking for a way to get this fixed.
Therefore I have two questions:
(1) Does anyone know how to disable hardware acceleration for Monogame only?
So disable it when Application/Activity has it enabled.
(2) Does anyone has an explanation for the black textures when hardware acceleration is enabled?
Is there a solution for this?

Hope one of you can help!
