[Bug]: Ball in BouncingBall, BallAcceleration and Test sim isn't showed

[physicshub]

Describe the bug

The simulations seems to work without errors, but the ball and all the components aren't always rendered. SimInfos works fine.
Sometimes randomly ball are rendered.
Seems like balls are rendered below the level of the canvas (see test simulation, that has collision, so if you resize the window you can see that some balls goes up).
So probaly the problem isn't the render but only the spawn position.

To Reproduce

1. Go to BouncingBall or BallAcceleration sim, try a few times changing page and switching between simulations
2. See that it's completely empty or if its rendered correctly

Expected behavior

It should always render balls.
