Follow-up Comment #8, bug #60356 (project octave):


[comment #7 comment #7:]

using Gnome on XOrg. I will try Wayland the next days.

Thank you Torsten! I have been trying to debug this myself, but progress is
very slow because I did not have any previous experience with either Octave or
Qt.

Anyhow, now that I discovered that Wayland is involved, I also came up with a
workaround: Force Qt to use XOrg like this:

    $ QT_QPA_PLATFORM=xcb /usr/bin/octave --gui

XWayland must be installed, which is the case for Fedora.

Also, using debug printing, I found out that the clipboard is emptied during
this call in QTerminal::handleCustomContextMenuRequested:

    _contextMenu->exec (mapToGlobal (at));
