AW: Indeed, this happens. I got vcl with debug and tracked it
down to the DRawingLayer visibility test (which decides if to draw at all):
rRedrawArea.IsOver(GetPaintRectangle()) returns sometimes true, sometimes false.
rRedrawArea contains the redraw area, GetPaintRectangle() gives the paint
rectangle of the object (e.g. 7200, 10500, 16700, 10500). First thought was that
it is a problem that the height for the hair line is 0, so i set it to 1, but
makes no difference. Next, a look at vcl:
In region.cxx Region::IsOver(...) the rect is converted to a region and
intersected with the RedrawArea. This is sometimes empty, sometimes not.
AW->SSA: To reproduce: New draw/impress, draw hor line (hold shift). Use cursor
keys to move right/left, You will find spots where it gets painted and where
not, this corresponds with Region::IsOver returning true/false.
