16249	Qt frontend doesn't set HiDPI attributes	Andreas Schneider		"The VirtualBox Qt Frontend doesn't set HiDPI Qt attributes, so the the rendering on HiDPI display is horrible.

See the attached patch fixes the rendering of the management GUI. More details are at:

  https://doc.qt.io/qt-5/highdpi.html

However the guest window still doesn't not render correctly. I think it uses images for that and needs to be adapted for that.

So the attached patch is only half of the story."	defect	new	GUI	VirtualBox 5.1.10		hidpi		all	other
