Sorry for not responding quickly. We're using C++, and I'm compiling with -Wall -pedantic -Wextra and not getting any warnings or errors. I agree that it's probably an overflow error of some sort, but 64 seconds seemed like such a specific number that I was hoping it might be something in WPILib. There is no output over netconsole. Looking at the DS Log Viewer, there seem to be spikes in dropped packets that correspond to the flickering.
