Discover acting strangly and konsole output

SUMMARY
***
Very often when I start Discover the window of Discover becomes only dark grey and white and behaves slowish and strange. Personally I think this related to the same thing as the wallpaper picker freezing and making plasma unusable https://bugs.kde.org/show_bug.cgi?id=470213 But I'm not able to check because I don't know how to start the wallpaper picker from the console. So I can't get output.
Anyway, when I start Discover from the konsole I get this output:
