Follow-up Comment #3, bug #55158 (project octave):

I tested on octave 5.0.0 (HG ID for this build is "7f6a50f73625)
result at attach file. This is excellent! I will wait this change on stable
branch. In my test octave-gui 100% utilize one core, when I try zoom in / out.

đťaybe it will be useful.. Strace output:
