Hello Robert:
Thank you for the insight. I will probably do a simple threading
loop for it and see if this solves the problem. I might have to play
with Locking the QtGlWidget and see if it runs clean without core
dumping.
Take care
Garrett

the scene became very Jerky. Playing with Qt's timer interval it

Not sure if this information is useful but I am also curious if

I haven't seen this, but it sounds like the timer has been given a
lower priority or simply implemented differently.
Using GUI timers to drive redraws isn't ideal, for solid framerates
you really need to run a separate graphics thread. For any serious
vis-sim work this is essential. For interactive apps GUI timers will
often suffice, but as you've found out you are at the mercy of the
Windowing toolkits implementation of its timers.
Robert.
