Navigation - Autodepth cause Blender 2.8 Official FREEZE

Hi all guys, working here in Blender 2.8 official, and as usual i use Navigation - Auto Depth ON.
But Blender freeze every about 5 minutes of work or less.
When i Disable the option, no more problem. But i used to it, and hate navigation without autodept.

My configuration is:
Windows 10 pro build 18362
Intel i7-5960x - 64gb ram
AMD Radeon Pro Duo Polaris 32gb + Amd radeon RX 580
