[Xmonad] [Bug] TwoPane Layout

[Robert Manea]

Hi,

i stumbeld upon some nasty behaviour in TwoPane layout. Reproduce
it as follows:

    * open 4 windows
    * switch to tall layout (slave area at the right)
    * put 2 windows into the master area (incmaster)
    * there should now be 4 equaly sized windows visible
    * focus a window in the slave area
    * switch to TwoPane layout

depending on which slave window had focus, TwoPane layout shows some
weirdly overlapping windows.

Bye, Rob.
