I'm having the same problem as can be seen in this video:

In addition, the edges of sniper scopes seem to be vibrating/shimmering in a similar manner, which I believe has the same root cause as the distant shadows.
I've tried changing various graphical settings (cache shadows, AA, shadow resolution, disabling Nvidia filters etc.) and tried reinstalling windows + CoD: Warzone, but nothing seems to help. Does anyone has a solution to this?
