I've noticed a very annoying and wierd error:
When using on a battery (unplugged from power source) - any horizontal movement of kinematicbody2D, like
velocity.x+= (a number)
there's a very bad-looking jitter and stuttering
Problem occurs on Lenovo IdeaGaming laptop AMD Ryzen 5 5600H with Radeon Graphics 3.30 GHz
The moment I plug the laptop to power source - it gets better.
(although - it's not ideal and could be better...)
