Serious problem with QGLWidget

[wysota]

Is this smooth enough for you (it rotates instead of scrolling, but the idea remains...)?

Back from sleep, work...

Thanks for the example wysota. I just found that the changes in my third post worked to solve the problem, but I also had to remove the timing routine that I introduced as a fix.

So again, thanks for working with me on this. I'll post the link of a working example or tutorial soon.
