Jitter in projects

[dest1]

Godot version:
3.11 & 3.2.1

OS/device including version:
Windows 10

Issue description:
I have jitter every ~2 seconds in my Godot projects. Did some test and reduced it to the basics.
I included a simple sample project with a moving kinematicbody2D that moves with:
move_and_collide(Vector2(120,0) * delta) in _physics_process(delta)
What i see is 3 intervals where the sprite jitters, near frame 71, 188 and 304 (and continueing onward). The profiler says the frame time, mainly idle time, is 0.073s on those frame numbers. Which is 4 frames at 60fps.

I have tried to bypass this with running fullscreen, exporting without debug, putting the move_and_collide in _process instead. It stays very visible.

Minimal reproduction project:
jitter_project.zip

Can you reproduce this if you set Rendering > Quality > Driver > Driver Name to GLES2 in the Project Settings?

Make sure that Godot Editor is not Switching to Remote scene tree
Check : Editor -> Editor Settings -> Scroll down to : Debugger -> Turn off : Auto Switch to remote Scene Tree

Yes, I tried with GLES2 driver, but nothing seems to change.
Switching to Remote scene tree was off already.
Also, for clarity: i have exported the project and when i run that, it's there as well.

I can't reproduce this on 3.2.1. Are you sure you don't have any background applications causing CPU spikes? That normally causes objects to stutter/jitter (for any application, really)

Also, what is your device info? Graphics card and CPU?

I have everything closed when i run it. And i dont notice anything when playing other games.
So i dont think so..
My system specs: AMD A8-7410 APU with AMD Radeon R5 Graphics (2200MHz)
Running Windows 10, Home.

I cant reproduce it on Linux with 3.2 but running .exe provided in the demo with wine shows noticeable jitters.
