Finally got some free time slots so I could compile the latest build today
(#5050) and test the changes you made last week.

Using the SerialPort example the CPU usage seems OK when just opening and
listening. When sending a simple 10-bytes textstring it still uses very high
CPU on the RasPi.

Also received a error message when pressing Close button, see attached
pics for info and I also include system info below...

[System]
OperatingSystem=Linux

Let me know if you want me to test anything specific or needs some
more/other
info.
