Kamoso crashes when clicking on the magic wand icon

As soon as I start Kamoso on Kubuntu 20.04, if I click on the "magic wand" icon (first icon on the left of the toolbar) the application crashes.

I opened https://bugs.kde.org/show_bug.cgi?id=431065 and it was closed as being an i965 Mesa driver fault, however producing proper debug information for Mesa and/or testing a newer version goes beyond my capabilities.

Still, it's a fact that Kamoso on Kubuntu 20.04 does not work properly on my system.
