Thanks for the response - did you test on 4.14 or 4.15?

Sounds like something went wrong with the test project - it should have transitioned to a white screen.

You should hit a breakpoint in AMyHUD::DrawHUD().

The first DrawItem should be a white tile item. If it isn’t try replacing the function with this:

void AMyHUD::DrawHUD()
{
	float fCentreX, fCentreY;
	Canvas->GetCenter(fCentreX, fCentreY);
	fCentreX = FMath::FloorToFloat(fCentreX);
	fCentreY = FMath::FloorToFloat(fCentreY);
	FVector2D min(0.0f, 0.0f), extents(fCentreX*2.0f, fCentreY*2.0f);
	FCanvasTileItem drawMe(min, extents, FLinearColor::White);
	Canvas->DrawItem(drawMe);
}
