3d model flickers when running examples/rocket/main.py run

[ephraim71]

Hey there!
I'm trying out this example.
examples/rocket/main.py run
My GPU is

glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa Intel(R) Graphics (RPL-S)

I see that the rocket model flickers :

Is there any setup step I'm missing?

My OS :

uname -a && lsb_release -a 2>/dev/null || cat /etc/os-release
