[Qt-interest] OpenGL Refresh Issue

[Willy P]

I found the solution.  There appears to be a bug in the QGraphicsView
or QTreeView where not having a frame around one or both causes this
issue.  If you look closely in the video you can see a one pixel wide
artifact on the laft side of the QGraphicsView.
