Bug with gmt text -F and transparency with @ (red@50)

[Esteban82]

The option with gmt text and @ fails. The other optios for transparency works fine.

gmt begin map png
    gmt coast -Rg -JH10c -Baf -Glightgreen -Slightblue
    echo GMT | gmt text -F+cMC+f40p,red@50      # Fails
    echo GMT | gmt text -F+cML+f40p,red -t50    # Works
    echo 180 40 | gmt plot -Sc1c -Gblack@50     # Works
gmt end

Just see this. In GenericMappingTools/pygmt#4708 (comment) I had an issue which sounds a bit similar to this one here; but I did not look at details yet. Did you test saving as PDF format? Wich OS you are using?

I got the same result with a PDF. I am using Ubuntu 26.04 LTS.

Thanks! This issue must be something else. I have the problem with GMT 6.7.0 for both gs 10.07.1 and 10.06.0. For me, the issue does not occur with GMT 6.7.0_8931e47_2026.01.12 for gs 10.06.0.
