It is still relevant. I've installed MacPorts version of Octave 4.0.1-rc4 with qscintilla @2.9.1_0 just the other day and editor is still blurry.

Quick googling revealed a possible cause:

Thanks Carlo.
The reason I asked for the QScintilla version is that I saw that some software had had similar issues (blurred display) specifically with QScintilla (not Qt nor Scintilla), see e.g. [1]. As stated in comment #2  (see link there in), QScintilla has an entry in the 2.8.1 release notes about retina related fixes.

I have no idea what it takes to retinize an app.
Anyway, in case it is of any help, the binary package
for Octave 3.8.2 at

http://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/test/2014-09-25-Binary-of-GNU-Octave-3.8.2-for-OSX-10.9.5/

is built using qscintilla version 2.7.2.

@Dear Pantxo,

Thank you for bring me such way. Yet i wish to use Octave GUI, and it seems that installation of Octave via Macport is a bit complex for me. Do you have any other solution? Thank you for your keen help!

@Xiong,

Another way to see if this issue is solved by recent qscintilla versions is to use Macports: their port of Octave uses Qscintilla 2.8.4, which should work with retina display.

Can you try to install octave with Macports?

I had a chance to make the test myself at work today with a non retina featured macbook. I thus couldn't see the real issue but I could see the output of "otool -L" (not B, sorry) on the gui executable. The qscintilla dylib name is 2.9.0 ... but qscintilla 2.9 hasn't been released!
AFAIR, this executable is produced using Macports and I am wondering if this strange version number doesn't come from a Macports specific versioning scheme.

Do someone have a clue? Can we add cdf to the recipients of this bug report?

Hi,

Then the executables should be in /usr/local/octave.../bin/octave-gui

Can you run the following command:

otool -B /usr/local/octave/directory/bin/octave-gui

Adapt the path, and report the output here.

Thank you Ben Abbott and Pantxo. I installed Octave from http://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/test/2014-09-25-Binary-of-GNU-Octave-3.8.2-for-OSX-10.9.5/, and i guess it is a binary installer.

This app may be useful in retinizing QScintilla < 2.8.1

Hi,

I see in QScintilla 2.8.1 release notes [1] that they now support retina display. Xiong, how did you install octave? Is your version of QScintilla older than 2.8.1, and if so can you upgrade it?

The core Octave developers use Linux operating systems, and I have no idea what it takes to make an application "retina" for a Mac.

If you can find out how it is done and submit a patch I could review it.

Respected Octave Developer Team,

       Thank you for bringing us Octave 3.8.2 Mac, which is marvelous. BTW, could you consider to retinize the Script Editor in Octave, please? This would better the GUI of Octave on Mac with retina display. Many thanks for your selfless and fruitful work!!!
