Yeah, the processor will glitch out after a couple hours on the battery. This is what happens when the voltage gets too low. Once you know what’s causing it it can be kind of fun to watch.
There is technically a potential for this to cause some kind of damage to the processor so it’s not recommended to keep playing when the glitches start.
If anyone ever has a dead dev kit please let me know, this low voltage testing is one of the things we are “Developing”
