Just to follow up on this issue. I just realized that if you install
gnome-tweak tool
[sudo apt install gnome-tweak-tool] you can actually choose between coherent or
independent behavior of your multiple monitors across workspaces.
Once installed, launch tweak and then click on workspaces.
Totally agree with Bruce!
I have two monitors. Let say I use LibreOffice on the left (primary) monitor
and a reference manager on the right monitor.
When I switch workspace (let say to do some programming) I don' t expect that
the reference manager keeps appearing?
This should be fixed. Or at
