Need Help. Really strange Camera "issue". Vibrates / distorts after packing

Hello, I need help. Run very well in preview at 100fps with 980ti and after paking in the past week. Now there is this “shaking” on all the surface, most evident on the
far objects. Please help me, sorry for my english.

I have this same issue in 4.11.2. Not sure if its a bug. The only way to work around it seems to be to increase the resolution of the game viewport. :\

Question, does your game viewport (while in the editor) also look very strange when you press G for game view mode?

Yes, 4.11.2

But no, in the viewport ALL RUN very good. Also in game mode, also in immersive mode (80fps with a 1440p display).
