[winswitch] Scaling on Newer Retina displays

[Shane Williams]

I have a user who is running xpra (probably 2.3) on a new
MacBook Pro with Retina, connecting to an Ubuntu system running xpra
2.4.2.  Various programs (notably xemacs or various terminals) display
as very small on his Mac (to the point where it's basically impossible
to read the text).  We've used the scaling setting to make these
windows larger, but by the time text would be large enough to read,
it's gotten so fuzzy/noisy that you can't really read it that way
either.

I've read the xpra web page about DPI and followed most of the links,
but it's still not clear to me whether there's a solution other than
scaling.  Is anyone using a high-DPI Retina display with xpra that
might have suggestions on how to improve the readability/usability in
this situation?


P.S. I don't have regular access to the laptop, so I can't easily
provide diagnostic information about it.
