Few physics bugs (still in 5.3.4f1).

Unity Engine

Hello, i would like to talk about few bugs related to physics/character controller (still in 5.3.4f1).

*) After switching to unity 5 (v5.2.2), many players started to report bug, that they are falling through ground (or they can walk trough objects). It happens randomly - collision between CC and some objects in scene is simply ignored.
Few times i saw this bug in editor (everything was fine with colliders and layers). And considering that respawning fixed this collision bug, it’s clear that problem is in character controller.

*) Character controller stucks/jumps.
Here i recorded video (few months ago) :

As i understand step offeset is triggered, when CC touches edges of collider.

I would like to hear if anyone of you also noticed these bugs in your games.
Maybe exist fix for these bugs?

Sweep tests are bugged with backfaces currently, for us.

Not sure if its related, but I recently reported a bug about casts becoming more and more inaccurate the larger (scale is 1,1,1 but object is large) the object is.

I sent a bug report

They were able to reproduce it, though for boxcast only.
At smaller objects only the hit distance seems to be off, but the larger the object, the more and more inaccurate both the hitpoint and hitdistance get.

If you use a much smaller object, does the bug go away?
