Check the line starting with 2461.  It's "bold" up to the middle.

This seems to happen for this positions: lines at the edges of my metacity window switching window, and from the first col to the one that hits the metacity window.

	Bug 401082 – double-draw issue

	The main cause of this bug was not expanding the cleared area to cover
	all the cells affected by the draw and forgetting to offset the clear
	by VTE_PAD_WIDTH.

	To counter the performance hit due to the expanded repaint area, each
	backend is presented with the opportunity to apply a clip to the
	exposed region before painting.

	This also fixes bug 333157,
