Thank you for clarifying things for me. So it sounds like the virtual backend
*can* provide what a 3rd-party VNC server would need on the output side. I will
look elsewhere for what would need doing on the input

Have rebuilt kglobalacceld with the full MR patch -- no change, as you expected

Will do - once I re-teach myself how. Been over a decade.
Ctrl+C might not work under the bugged condition within the VNC session - is
there any problem with doing that in a VT, or in a parallel SSH session

Sorry, amendment to the above on further investigation.

Further data point: I just added a systemmonitor plasmoid to my panel to show

not show any heavy activity.

Have just updated to 5.24 and have to be honest, this is not a very good

- Thick blue border around centred window
- No reflections

Maybe I'll understand when I see the new version, but I don't see how removing

this has been done though.
