You need to not be defining those pointers at the top, they don't do anything and the syntax is weird.

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.
