Text scale on HiDPI display using Direct2D renderer

I have 4K screen (3840x2160) and scaling set to 200% in Windows. When I use GDI or GDI+ to draw text it looks fine and scales as needed, but when I use wxGraphicsContext (or wxGCDC) with Direct2D backend the text is drawn with 100% scale. Images are drawn with correct size. Only text is affected.
GDI:
Direct2D:
Direct2D (with image):
Is there a way to fix that? Scintilla draws text with proper scaling when I set it to wxSTC_TECHNOLOGY_DIRECTWRITE.

Sure. I'll do that once I figure out how to create tickets there.

Here's the ticket. I'm not sure if it's actually created and visible to anyone else. This wxTrack system is utterly unusable.

The ticket is visible, thanks.
Could you check if the problem can be seen in the "drawing" sample where you can switch between different renderers? If yes, please add that information to the ticket.
