not sure why this happens, but make sure you check out the phys.body.velocity example patch that demonstrates how to query and control the velocity of a rigid-body:

you probably want to make sure you are upgraded to 6.0.8 too.

Thank you this solves my problem :)

Controlling velocity is a good workaround but maybe it is better fix the problem around restitution
I searched in the Bullet forum and i found this thread
the administrator speak about:
"enable split impulse, it will prevent the added energy (velocity) from penetrations.
m_dynamicsWorld->getSolverInfo().m_splitImpulse = true;"

Is possible to control split impulse in jitter?

thanks for digging that up!
i will look at implementing this as an option to

I’m happy if this can help you
I wait for news

Thank you for your help
