I have drastically simplified the problem reproducer now. Attached as obifluidtest.zip.
The problem: The Obi Fluid dropping from above tunnels through the non-static small Cube and only collides with the larger GroundCube below.
On my plain installation of Unity 6000.5.2f1 (6.5) without any additional components or special GPU tools outside of Unity, it shows the issue on a Macbook Air M1 and a Macbook Pro M2, both with 16 GB RAM when Compute GPU Mode in the Obi Solver is enabled. When switching to Burst CPU mode it works fine.
Inside GPU Mode the trigger for the issue to appear is increasing any side of the GroundCube object above 8. Currently in the the reproducer project it is 8.1x8x8.
From support I received already a reply and they couldn't reproduce it on comparable hardware.
