Public bug reported:
Binary package hint: metacity
_NET_WORKAREA is not calculated correctly for the case of 2 monitors as
follows:
- leftmost monitor: 1024x786
- rightmost monitor: 1440x900
Leftmost monitor has a strut along the left-side, so is 786 pixels in
height
The _NET_WORKAREA calculation uses
meta_rectangle_get_minimal_spanning_set_for_region to find all regions
that are not covered by struts. However it finds such regions within the
whole "screen" - a rectangle of width 1024+1440 = 2464 and height
786+900 = 1686
As a result, meta_rectangle_get_minimal_spanning_set_for_region returns
a region below the viewable area of the left-most screen:
x=0, y=786, width=1024, height=114
This is outside the viewable screens.
The _NET_WORKAREA calculation includes this region, with the consequence
that the left-most strut is effectively ignored.
