--- Comment #1 from Alex Thurgood <iplaw67 at tuta.io> ---
Confirming with my master build 6.0alpha1.

The main lag seems to appear for me in the handling in bitmap.cxx, line 945:

    Bitmap aBmp(GetBitmap(aDstRect.TopLeft(), aDstRect.GetSize()));

which is called by function :

void OutputDevice::DrawDeviceAlphaBitmapSlowPath(const Bitmap& rBitmap, const
AlphaMask& rAlpha, tools::Rectangle aDstRect, tools::Rectangle aBmpRect, Size&
aOutSize, Point& aOutPoint)
