Screenshot of Air for netbooks theme, with Krunner open
When choosing the Air for netbooks theme, Krunner has too much transparency which makes it unusable to use.
See attached screenshot, which also shows some other issues with the air for nb theme.
Another thing is, that it is also not possible to change the theme for krunner (as a workaround), see my related bug 317121.
