Tesla has greatly improved the smoothness of FSD visualizations in FSD V12.5.6 by fixing a 4-year-old bug. The fact that Tesla knew about this bug suggests it may have been difficult or time-consuming to fix, and they preferred to dedicate resources toward new features, but now that it’s fixed, users with FSD 12.5.6 are reporting much smoother visualizations.
Bug Fix
While not detailed, this bug that plagued the rendering pipeline had been an issue in Tesla AI’s backside for four years, according to Ashok Elluswamy, the head of Autopilot and AI at Tesla. Funnily enough, Andrej Karpathy, the previous Director of AI at Tesla, replied, “omg.”
Because we fixed a four year old bug in the rendering!

It sounds like Andrej knew about the bug in the rendering pipeline during his Tesla days but was also unable to fix it, likely due to other priorities. We’re glad to see Tesla is going back and working on squeezing the most performance from its hardware—in any capacity.
Smoother Visualizations Video
The updated visualizations are considerably smoother after the bug fix. What’s immediately noticeable is less jitter in vehicles around you and vehicles starting to show up from further away. This is a fantastic update, as it helps to provide better information for the supervising driver about what FSD sees around the vehicle.
We’re looking forward to what else Tesla can do to optimize and make its visualizations look even better. In the meantime, check out these two videos below that include the improved FSD visualizations.

Installs on Oct 22
We first noticed FSD 12.5.6 on update 2024.32.30 on October 8th, right before the Robotaxi event. FSD 12.5.6 is more than just bug fixes; it includes major changes such as new FSD profiles, improved lane changes, and changes to Auto Set Speed. However, it's still only available for early-access customers. While Tesla’s AI team was likely focused on the event and has now earned a well-deserved rest, it appears that this FSD release may see another revision before it is expanded to regular customers.
