I am helping to develop an OpenGl plotting system with ToddAtWSU. The plotting system works well, except when another window covers the plot, however briefly. When covered and uncovered, the drawing slows down to a halt and hangs the system. Someone I work with mentioned a "backing store" and trying to disable it. Looking through the forums, there is mention that "...I think backing store can be disabled" but not concrete yes/no. Is this possible in Qt4.1.4+? If so, how do you do it? We are interested in if this solves our problem in the drawing.
Mucho Thanks in advance
