- fixed: high uptime was causing overloads in uint32_t and float structures (float losing loss of precision) - this caused any computer online for more than a few days to experience jankiness with internal animations such as rotations and shader timers. Unfortunately, this sounds the death knell for 32-bit platforms, since uint64_t is now required in time-critical structures, which will hurt performance tremendeously, but 64-bit systems will be unaffected.
