KDE taskbar overlaps fullscreen WinXP guest when switching to it with mouse click

[Dmitry Grigoriev]

Host: Gentoo Linux x86_64, KDE 3.5.9, VirtualBox 1.6.2_OSE. Guest: WinXP SP2 with VirtualBox Additions installed, mouse integration=on, fullscreen=on, autoresize guest display=on.

To reproduce: =============

0. Ensure you have multiple desktops in KDE, Desktop preview applet on taskbar, and hotkeys to switch between desktops (I use Super+F1...Super+F4).

1. Open WinXP guest on a separate desktop in fullscreen mode (I use Desktop4).

2. Press right Ctrl, then switch with keyboard to another desktop (I press Super+F1).

3. Switch back to WinXP by mouse-clicking desktop4 in desktop preview applet on KDE taskbar. You'll get fullscreen WinXP but still visible KDE taskbar.

Notes: ======

1. If you switch to desktop4 with keyboard (Super+F4 in my case), it will be ok.

2. To hide KDE taskbar, I press right Ctrl+Q (shutdown dialog), Esc (cancel shutdown dialog).

3. VirtualBox 1.5.x was ok (I don't remember exact version, probably one still last unmasked by Gentoo maintainers; I unmasked 1.6.x manually).

Note 4: WinXP is 32bit; it was installed under VBox 1.5.x; I upgraded to 1.6.x after that.

I thought it was not bug but feature :) And I miss it in VirtualBox 2.0.x Such additional full screen mode when hiding vbox top menu (machine devices help) and bottom with indicators, but still having hosts taskbar would be very helpful.

Please reopen if still reproducible with VBox 3.1.6.

Bug still exists in VBox 3.1.6 with updated Guest Additions. Compositing enabled.
