1 pixel width line rendering issue
Message 1 in thread
Lines of non-0 width (for example 1 pixel width) result in a
strange(?) behavior in QGraphicsView (at least on my platform, Linux,
XGL). Pixels belonging to such a line are drawn with +/1 pixel
position accuracy or are not rendered at all depending on the position
of the object in the scene. This results in a visible "jitter" when
scene is being updated. Same problem occurs for QBrush patterns.
0-width lines are always rendered correctly (no jitter and no pixels
omitted).
