[Andrey Kuznetsov <kandrey89@xxxxxxxxx>]

Hi,

So for now I've had a chance to test the motherboard project on my Retina
macbook display.
eeschema: horrible zoom, feels like elastic band zoom and I have all scroll
wheel accelerations and similar disabled, zoom response is super laggy,
cannot work like this, will need to make schematics on windows.
pcbnew by order of slowness:
legacy - pretty slow, zoom lag is major, boo boo
modern (fallback) - decent, but the lag can be felt, zoom lag is minor
modern (accelerated) - almost cannot feel the lag, very nice, nice zoom
responsiveness

I'll report tomorrow on 5K LG display.
