System Information
linux 64

Blender Version
daily build. But this issue was in previous builds.

Short description of error
i found big problem with instances. Sometimes they go away from its origin when i hide original group in other layer or when i switch Material Shading.

Here is my video demonstration of the problem: http://youtu.be/N2tAyJPW8xM
Here is the file: https://dl.dropboxusercontent.com/u/26887202/blender/temp_group_issue.blend

Exact steps for others to reproduce the error
Open the file. Switch to Material Shading. You will see that instance go away from its origin.

Think I could reproduce it too (making a render hid some plants here)… Thing is, it’s very hard to work on such a big scene/file, we need simple cases to investigate if possible, can you reproduce it with a simple supligroup particle system?

Uhhhh… This is the return of the ugly crap - Antony, you fixed a somewhat similar issue the other day iirc?

Anyway, @PaulGeraskin, cannot reproduce the issue with your file so far.
@bliblubli with your file issue shows up for me, but only with internal engine, with Cycles everything works fine…

Antony, Lukas, maybe you have some ideas?

It looks like the exact same issue and in fact can't reproduce it here. Can you check with recent buildbot? It should be fine now.

@bliblubli I'm not sure what your issue is, but changing display modes here works OK

Ah, alright I see it now, it's on rendering. Lukas should know better what this is.

No, it's @bliblubli's issue but that's a rendering issue and probably a separate issue too.

@bliblubli: Made a new report (#44248), better to stick to one issue per report. :)
