Not sure if this is with every door ingame but at least the ones in Girna if you move around a doorway (with the door open), some objects disappear that you should be able to see.

See the screenshots. In the first screenshot many of the hill objects have disappeared, if I edge forward slightly as shown in the second screenshot they are rendered suddenly, you can also see an enemy is included in the objects hidden.

This is game breaking and puts those taking cover in houses at an extreme disadvantage. {F18704} {F18705}
