The Octave Maintainers are getting ready to release version 6.1 of Octave.  It is possible, maybe even likely, that this bug has been fixed.  Could you try the release candidate 6.0.90a at alpha.gnu.org/pub/octave?

My opinion is that octave ha a problem with the dpi settings.
See in bug https://savannah.gnu.org/bugs/?58704 the file MyPlot_BugReport_ScreenShot.png.
It is done on a 4K monitor with 150 dpi on Windows 10. The font is too small for the size.

If you describe that the monitor size changes because of RDP it could be that the event for changing screen resolution is not handeled correctly.

Crash occurred after the following working steps:
1. Remotely connect from W10x64Pro (laptop single screen) to W10x64Pro (dual monitor) using buit-in RDP over a VPN.
2. Open octave, launch a script at the remote machine.
3. Disconnect RDP session. Take a coffee.
4. Reconnect.
---> oops, Octave is no longer running. Script was supposed to take like 50 min to complete.

Testing the crash:
---> the exact same script and data competed a run without a crash in a different machine using only a local session (no RDP).
---> the exact same script and data competed a run without a crash at the host machine using chrome remote desktop.

Personal note:
A screen resolution change is involved when using W10RDP built-in client (host has two screens, laptop has only one), whereas no src is involved using third party remote desktop apps. Hence I think the screen resolution change may be the one to blame for the crash.
