Hi,
Is there anyone who regularly builds the development version of Octave
for Windows or for macOS with a HiDPI / Retina display that can test the
attached patch for me?
I have seen some reports that the Octave GUI editor looks pixelated on
HiDPI displays. The attached patch is supposed to fix this. I have no
such hardware to test on (donations welcome), but the patch doesn't make
things any worse for me.
Can anyone test and confirm whether the patch improves the appearance of
the editor? Worse? No change?
Thanks,
--

Mike,
I regularly build the development branch on macOS on my MacBook Pro with a HiDPI / Retina display.
However, I don’t see\notice pixelated problems. fwiw, building with your patch looks fine to me as well.

I don’t see a problem either on my MacOS with Homebrew. In fact, I don’t see any difference with and without the patch.

It does make a difference in Linux, solving pixelated text in Octave's editor (at least) in KDE with hidpi screen scaled to a non-integer number.

I think the non/integer pixel ratio must be the deal. I did.a quick test and on all three of my displays, the pixel ratio is always 2.0 or 1.0 regardless of which screen and how I set up the scaling. Maybe there is something with MacOS where not integer pixel ratios are handled under the hood and it fakes exactly 2.0 or 1.0?

Thanks for testing.
Any Windows testers?

At the very least, I would like someone to verify that the patch does
not make things any worse, even on a normal 96 DPI screen.
But yes I would like a test from someone who has a version of Windows
that supports DPI scaling and a high-resolution screen to test Octave
with and without the patch applied.
This patch has already been proven to be beneficial on GNU/Linux systems
with HiDPI scaling enabled. If no one volunteers to test on Windows, I
will probably just apply it on the default branch for Octave 5 and we'll
see if anyone notices later. I would really like to apply it on the
stable branch with some testing.

Hey Mike,
Can we hope this patch to be part of an eventual Octave 4.4.1?
Thanks and best

Hey Mike,

The minor releases are typically only for bug fixes, and this is
very much a feature addition. That doesn't mean we can't make an
exception, but it should be debated first.

I would call this a bug fix, I think it is entirely appropriate to make
on the stable branch for 4.4.1, and I was planning on doing so.
This patch changes the default value of a Scintilla internal setting,
that the Scintilla docs themselves say should be a reasonable default on
any modern graphics system.

Hi Rik and Mike,
I understand the risk and hesitation. Any final decision is fine to me, although my hope is for a fix being released relatively soon as it's quite uncomfortable working with the editor at this point.
Thanks!

Is this a patch for bug #49053 or something different? My comments
are directed towards that bug.

It's something different. Mike's patch is about a Linux-specific issue of
the editor on HiDPI systems. The patch does not affect the other systems.
Bug #49053 is about plotting (and is fixed for me by the recent patch of
John Swensen; sadly a bit too late for 4.4).
Bye
