I had this issue. Sun shining through objects (buildings, trees, ground, etc.) I have an AMD APU and using CCC I had made a DayZ profile. Make sure everything is set to use application settings.

Not sure. One was south east and the other was adjacent.

If there's a possible map key binding, why does it only open a black "map". I stated in the report that action bar worked, however a map key should work too. Setting the binding works but it doesn't show a map. I don't think it's your issue with hardcoded bindings.

Works perfectly for me as well. I use 3rd person almost exclusively.

I had a can of tuna, I believe it was, stuck in the very back of a car trunk. I even glitched with vault into the middle of the car and still couldn't get it in my vicinity.

This happened to me. Try logging into a different server and while you're waiting for you to spawn in, hold W, sprint if you can. Collisions seem to be off/glitchey while loading in. I did this to get unstuck.

Can confirm this. I don't believe it was my machine, but I had logged into a hospital only to be attacked by an invisible zombie. I switched servers to get away. It's hard to run away when you can't see your attacker.
