Version: (using KDE 4.3.1) OS: Linux Installed from: Fedora RPMs If you select filters in the taskmanager's configuration, like "Only show tasks from the current desktop", you will get wrong panels for the other desktops that desktop grid shows you. Like, if I have opened programs A and B in desktop 1, and program C in desktop 2, and I am currently in desktop 1, when I activate the grid, I will see two panels with program's A and B minimized windows. I think that this is not the desired behavior for this feature.
