Dear colleagues,
I don't know if anyone else has had this problem. Over the weekend I upgraded my Mac
to Tahoe (26.1) and as soon as I opened Gretl, the text was blurry. I enclose a
screenshot, but I don't know if this really does justice to the problem. I am certain
that until I upgraded all the text was crisp and easily readable. I have changed settings
on the Mac to reduce transparency, and have tried various fonts in Gretl. Nothing seems to
make a difference. Gretl is the only software on my system which appears to have this
problem.
My guess would be that gretl is the only program on your system that
uses the GTK framework for the windows and graphical stuff (for
cross-platform technical reasons). If you're willing to do some more
testing, you could perhaps install another program that uses GTK,
perhaps something like GIMP (
https://www.gimp.org/downloads/ -- however,
I believe that the GTK version is different there, so it may not be a
definitive test).
I don't have access to a Mac running OS 26.x - are you saying that the
problem did not appear on the initial OS version 26.0, or did you skip
that version?
I am using Gretl 2025b, and the system is an iMac (2020) with a
27" built in Retina display (5120 x 2880).
If anyone has suggestions they would be very welcome. I know that 2025c will be released
soon, and hopefully the problem will be fixed then.
You could try a recent Mac snapshot to test that, but I think it's
unlikely that it's already solved.
thanks for the report
