 It seems portal gets partially black when looking at then from certain
 position (seems there is also a frame rate drop when it happens) but
 doesn't happen to everyone (eg jorrit cannot reproduce)

 It was seen happening from up to bottom and from right to left, the
 relative position of the geometry on the other side of the portal remains
 right but it's just covered partially with blackness.
