Since Chrome updated to version 74 we have a bunch of crash reports rolling in regarding physics interactions. These are all coming from Chromebooks. These same machines worked just fine in previous versions of Chrome, but now have a 100% crash rate. This is independent on the specs of the Chromebook. Windows computers running Chrome 74 with far worse specs run everything just fine with no crashes.
Different crashes we have seen are when an explosion force explodes recently instantiated geometry with an outward force, when 3 or 4 rigidbody spheres are bouncing or rolling on the ground and also when a character controller pushes 4 or 5 cubes together. There is also an instance where an explosive force makes every other rigid body in the blast radius just disappear. That last one doesn’t crash the game or even create any logs but it ruins the game logic when half of the stuff the players are supposed to interact with disappears.
We are an educational company, so a very high percentage of our users are using Chromebooks. Has anyone else been experiencing issues with this? I have some crash logs from a developer build that point to what appear to be different sections of the physics pipeline (though I’m no expert, so maybe they’re very related).
