GIMP does not support Mac Retina displays

Hello - I am an amateur photographer, satisfied user of GIMP on Mac computers; an iMac 27" at home and a Macbook Pro with 15" Retina displays, that I use on the road. GIMP does not support my Retina high resolution display; window graphics and text appear jagged, and, while displaying the same picture on the iMac and the Macbook, the Retina picture appears to be lower quality.

It is a pity that this wonderful program, ported to the Mac with native graphics, does not support these displays.

This is of course a request for an enhancement; will you plan to support high resolution displays in the near future?

Hi Maurizio,

thank you for reporting this. The Retina display problem is already known and there are two bugs in our Bugtracker for this:

Bug 682178-Offscreen windows render into low-resolution pixel space [1], Bug 686454-Gimp Canvas Content Looks Distorted and Pixelated on Macbook Pro Retina [2].

If you can provide more information on this, may it be observations, technical information or whatever is constructive, your comments on these Bugzilla bugs are welcome.

The current state of development as I heard on IRC: one developer already made bugfixes but found nobody with a Retina display to test it. Perhaps we can create a new temporary development branch in our Git repository for these bugfixes, get an OS X build from it and somebody with a Retina display is willing to test (perhaps you?). The quicker we find somebody, the quicker GIMP supports Retina displays.

From a technical point of view the platform specific code for rendering on OS X is in the underlying graphics library GDK or Cairo. Can anybody clarify which is the right one in GTK2 and GTK3? If we get stuck we should ask there to build the necessary foundations.

Kind regards,

Sven

@Sven, If I understand you right, you want to know what library gtk is built with? I build gtk with the quartz backend for native OSX builds.

Hope that helps.

No problem, provided that 1) my "GIMP on OS X" installation, from the distribution built by Simone Karin Lehman is not affected, i.e. if I can install this
test executable in a directory different from /Applications; and 2) my personal
scripts, fonts, plugins, ... under ~/Library/Application Support/GIMP/2.8/ are not
affected. OK, I could backup the whole stuff, but... And, well, in about ten
days I am planning to leave from home for a short trip in camping car wit limited/no web access...
