I’m very pleased with the new KDE. With the exception of the polkit argument that’s going on every new release of KDE brings fresh delight, and I hope it never stops.

There’s one little thing it took me a short while to realise and so is worth mentioning here. I use “Desktop Grid” and “Present Windows” a lot and have them mapped to the top corners of the desktop for quick-access. After upgrading to KDE SC 4.4.0, my panel started disappearing whenever I used “Desktop Grid” and, while it’s not exactly a problem, it doesn’t look very good. The panel always disappears in “Present Windows” but that is expected behaviour.

The reason I discovered is that “Desktop Grid” now includes a per-desktop “Present Windows” by default, so if you have multiple windows open in a desktop, they will be “Presented” within that desktop in the grid view, and for this reason the panel disappears. Some may like this feature, and I see how it could be very useful, but I don’t want it. As I have, you can turn it off:

System Settings -> Desktop -> Desktop Effects -> All Effects -> Desktop Grid (Configure)

Uncheck “Use Present Windows effect to layout the windows”.
