I use kazam to record libreoffice impress presentations but since moving to kubuntu on ubuntu 20.04 there is a flicker when the screen updates. I need to record the mouse because I am often demonstrating how to use impress to my students.
The flicker is not visible at recording time. Only on playback.

Kazam Kazam NCC-"80102" 1.4.5
NVIDEA 340 drivers
This used to work fine.
Any idea of fixes or alternates to kazam?
Update and further question
I have just installed simplescreenrecorder to see if it fixes the problem.
I'm definitely recording - the preview box is updating but despite recording a 2 minute clip I'm only getting a 262byte file.
