Shrinking VehicleWheel when using physics interpolation #72207
Description
Godot version
3.5.1.stable
System information
Windows 10, RTX 3070, driver version 528.24, both GLES2 and 3
Issue description
Physics interpolation causes the child mesh of every wheel to visually shrink. This change is smooth, when the physics FPS is equal to, or a multiple of, the screen's refresh rate. Otherwise, it causes jittering. The shrinking depends on driving speed and physics FPS. Higher speeds generally cause more shrinking. When the vehicle slows down, the wheels return to their normal size. Lower physics FPS also lead to shrinking.
Steps to reproduce
Play the reproduction project for a few seconds. No user input is needed. Results are inconsistent, even with identical settings. By default, the physics FPS is 60. Changes to it, or to the monitor's refresh rate, should lead to different results. The shrinking should only occur while physics interpolation is turned on.
