Missed rays in reflections/refractions with large scene extents

[pokoy]

I have a scene where I have placed objects (mountains) far away (20 km) in the scene and I need them to be reflected in scene objects closer to the camera. This causes artifacts on window panes in refractions and in places that reflect these panes.
I know there was a value in the daily builds for that but it seems it has changed. Did this setting change to 'Enviro distance' now? What side effects will it have when I change the value from the default 1 000 to 20 000 or even 30 000?

Could you show an example? I checked this and it looks pretty ok. The teapots are 20km from camera.

Enviro distance is not the thing. It's for global volume. I am afraid this would be problematic for all the renderers. Usually, when i know my scene extents will reach over 1*1km, i usually start building the scene with meters as system units. 20km is truly extreme value... what are your system units?

Thanks, at least I know that enviro distance does something different.
Maru, I guess the problem will start to appear when you make the glass panes thinner.

Here's a report from way earlier where it happened for me:

I'll have to come up with a different solution in this case, I may be able to render the mountains out and map them on a plane closer to the camera.
