Hi,
I have a QGLWidget inside a tab (page) that initially starts out not
displayed. However, when I view that tab, often the GL window has
garbage in it (appears to be uninitialized video buffer memory), and
when GL drawing occurs, it flickers almost as if the one of the buffers
(front or back) is permanently garbage. The rest of the time, the
widget initializes properly. This seems to be some kind of race
condition, and it only started appearing after I put the QGLWidget in a
tab instead of displaying it immediately upon app startup. Is there
some initialization that I'm missing?
Thanks,
-geordan
