I have install the latest version of KDE Neon. And tried to use programs like Flameshot, SimpleScreenRecorder, OBS, Kazam or they alternatives. And all they record black screen instead of desktop picture. Hovewer, the most interesting of this situations is that all these programs correctly works on Ubuntu with Gnome. Do you have an idea why it's happening?
