Although very weird, I found a correlation confirmed by experience. If linux packages are updated, I need to manually reinstall the mesa packages to have a working kwin in next session (surely manually reconfiguring mesa would be enough too, but I didn't try). If I don't do that my plasma desktop and application windows appear in black.
