Update of bug #46910 (project octave):
Item Group: Performance => Regression
Status: Need Info => Confirmed
Release: 4.0.0 => dev
_______________________________________________________
Follow-up Comment #10:
I can confirm that the figure can be plotted very fast on Windows 10 with
Octave 4.2.1. I also cannot re-produce with Octave 4.3.0+ hg id "5570b0f12112"
(qt4).
However, I am seeing the issue again on a more recent build with hg id
"c2ef0eddf6bc" and 3 later builds that were build with qt5.
When issuing the print command, Octave stops responding and "gs.exe" uses one
core indefinitely (25% CPU usage on a quad-core). After 20 minutes, it was
still not finished. It also doesn't stop using the CPU when I kill Octave.
This can also be re-produced with:
plot ([0 1]);
print ("plot.eps")
Printing succeeds and is fast with "graphics_toolkit gnuplot".
I don't know whether this has something to do with the switch from qt4 to qt5
or with something else that has changed between these builds.
Marking as a regression on dev.
