Posted to the mailing list, not the tracker:

Hello team,

Congratulations with Octave 4.2 release!

Unfortunately still some problems with figure saving:

   1. With

graphics_toolkit('gnuplot'): I can't get colored text in figure legend
   (the same code works with gnuplot)

   2. With graphics_toolkit('qt'):

   can't save figures with property 'visible', 'off'

Code example:

%graphics_toolkit('gnuplot')
graphics_toolkit('qt')
fh=figure(1,'visible', 'off');
plot(1:8, magic(8)), grid on

lh=legend(...
  { '1){\bf bold font}' ...
  , '3)\color[rgb]{0 0 1}{\bf blue text}' ...
  });
print(fh,'png', '-dpng')

Output message:

Mesa warning: couldn't open dxtn.dll, software DXTn
compression/decompression unavailable
GL2PS error: Incorrect viewport (x=0, y=328577624, width=0,
height=328577672)

Thank you for your bug report. This has actually been reported and fixed (see bug #44765). The fix has not been released, you can get it with Octave 4.2 or by building Octave from the development branch.
