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.

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.

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 just tried GIMP and the text is clear and crisp. As you say it might be a different GTK version. > 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 skipped 26.0, as I am always wary about first releases, so I don't know if there was a problem with 26.0. > 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 > I'll try a recent snapshot to see. Thanks for the suggestion.

Thanks Allin. Indeed mine is an Intel Mac. It would be great if the intel version can be updated as well.

Hi Allin, Thanks very much for the update. I have just tested on my Intel Mac. Unfortunately it seems to make no difference. The text is still blurry, about the same as before.
