QGraphicsView drawForeground affecting pixmap items

[kegon]

Hi,

I have a QGraphicsView with a QGraphicsScene and a single QPixmapItem displayed in the scene/view.

I want to put some extra information layered on top so I use drawForeground() to place some text in a rectangle as a kind of on screen display.

The issue I have is that there appears to be an additional rectangle drawn near the pixmap using the same brush and pen I used before. When I manipulate the scale and location of the pixmap item, the extra rectangle is drawn again in the new position/scale, The foreground image "buffer" gets full of extraneous rectangles. A resize event clears the foreground buffer and gets rid of all the extraneous rectangles except the additional one on the pixmap.

Am I supposed to be clearing the foreground buffer ?

Occurs on Mac and Linux.

Adding setViewportUpdateMode(QGraphicsView::FullViewportUpdate); seems to solve it.
