Ever since update I've been getting random freezes on loading screen with no apparent cause, this includes with addons completely turned off.
Can happen with any loading screen: switching zones (wayshrines or teleport to player, walking into public dungeon), porting to houses, loading into character, loading into character selection menu, even quitting game can get you frozen black screen.

I found no logic or connections between these, can be fine for 4 hours straight and then freeze, can be as soon as first port.
Other similar but not the same thread here suggested turning off new feature - limit background FPS. Does not help here.
