           Summary: window placement has dead areas on non-rectangular
                    multihead/xinerama/mergedfb screens with kicker on
                    smaller screen
           Product: kwin
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kwin kde org
        ReportedBy: co kevquinn com


Version:            (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          gcc version 3.4.6 (Gentoo Hardened 3.4.6-r2, HTB-3.4.4-1.00, \
                ssp-3.4.6-1.0, pie-8.7.9) 
OS:                Linux

I have a non-rectangular merged-fb (radeon - it simulates xinerama) setup on a \
laptop; 1024x768 on the built-in panel, 1280x1024 on the external monitor arranged \
thus:

    ._________._______.
    |                 |
    |                 |
    |                 |
    |..........___2___|
    | x    x  |
    |___x1___x|


Normally I place the panel at the bottom of the larger display (at 1) and everything \
works fine.  However if I place the panel at the bottom of the smaller screen (at 2), \
there's a "dead" area below the bottom of the smaller screen on the larger screen \
(marked with 'x's), such that when moving windows around, the refuse to move into the \
dead area.  Windows can expand downwards into the dead area, but can't move into it \
completely.  To be accurate, the title bar of the window refuses to move below the \
level of the panel on the smaller screen.

It seems that the placement algorithm is bounding the window movement by limiting the \
base of the title bar to the top of the panel, rather than the base of the screen in \
which the window is placed.

Attachments to follow:
xprop -root (panel on larger screen)
xprop -root (panel on smaller screen)
xprop (window with panel on larger screen)
xprop (window with panel on smaller screen)
