Graphics::drawImage 100x slower on retina since Logic 10.5, than on non-retina

here is the culprit:

CoreGraphicsContext::getPhysicalPixelScaleFactor returns incorrect value (standalone app)

On Mac g.getInternalContext().getPhysicalPixelScaleFactor() seems to return 4.0 in a standalone application (I saw there was another thread from 2017 that had to do with VST, but this is not even running inside a plugin). Inside CoreGraphicsContext targetScale is 2.0, which is then further multiplied by the CoreGraphics context scale factor, resulting in 4.0. When USE_COREGRAPHICS_RENDERING is set to 0, the returned value is correct and is 2.0. Thanks, George.

For my retina-optimisation i use the physicalScalFactor and it returns 4 instead of 2, which i guess is a bug, so the internal buffer was created was much higher resolution than required.
