Version:            (using KDE 4.2.4)
Installed from:    Debian testing/unstable Packages

When activating panel autohide, moving the cursor close to the screen edge will make a small (5-10 pixel) blue line appear and indicate that the cursor is close to the edge.
This small line intercepts the clicks that windows should get.
Pretty minor.

the effect needs to be moved into kwin's compositing effects.

Still in KDE 4.4. Only happens with Compiz, not with KWin. But there was
no problem under 4.2.

I think the initial description is slightly wrong.  What appears to be happening is that in panelview.cpp the function which creates the unhidetrigger for the toolbar checks if composite is enabled and if it is it increases the trigger window size by 30 (pixels I presume).  If a full screen app is loaded this 30 pixel window should be lowered below the fullscreen app. 
The 30 pixel window is enough to block access to a windows toolbar in a fullscreen rdesktop session.

Do you reproduce with kde 4.4.4 or 4.5 beta ?

Hi,
   Yes with the kde 4.4.4 build it is also the same.  On further checking even the 1-pixel window which activates the toolbar causes problems e.g. a full screen krdc to windows which has a hidden toolbar means the windows toolbar cant be activated as the plasma panel captures the mouse. Would the solution not be to ensure full-screen apps are above plasma in z-order ?

This still happens with KDE 4.5.1. Auto-hide makes the horizontal scoll
bar in gwenview and the page switcher in okular unusable in fullscreen
mode.

Happens for me with KDE 4.6.2 (tested with Kubuntu 11.04 packaged
version). This is quite annoying when using VirtualBox or full screen
Flash video players (with controls at bottom) in fullscreen mode.

For me, there is no visual artifact associated with this, just the loss
of click events meant for the fullscreen app, from the area where the
auto-hide panel would appear.

I don't have any more issues with this. I have KDE 4.6.5, but I don't
know when it disappeared.

I'm on latest kubuntu beta, kde 4.7 and this bus is still an issue - IT
only happens when desktop effects are turned on and is caused by the
drawing of a rectangular area where the panel should be which helps with
the drawing of the highlight before the panel is activated.  This
rectangle traps the mouse clicks preventing the active application
receiving them...

Fixed in at least 4.8; clicks are not intercepted within the blue glow
area for me.

In the latest Kubuntu beta running kde 4.8.00 this is NOT fixed... Same
as before if I have my bottom panel on autohide launch a fullscreen krdc
session to a windows terminal server all clicks where the panel would be
are prevented from reaching krdc.

If I disable desktop effects or make the bottom panel not autohide there
is no problem

In Gentoo running kde 4.9.0 bug is not fixed.
And there is not visual artifact, just loss of click events.
