Custom viewstyle fails to render in layout on latest Service Release

Well… me again.

I’ve spent some time figuring out how to create a custom ViewStyle with hard shadows (but in a light gray tone). I made a copy of Arctic and tweaked a few parameters, one of which was the gamma output to get the soft gray look I needed.

I was satisfied as it was ok for my needs.. everything was working fine, until I updated Rhino today.

Now the problem is that this ViewStyle is not rendering correctly inside a detail view (it was working before the Rhino update).

Since I’ve also been chasing a few other Rhino bugs today, I’m not sure whether I changed something accidentally or if this is related to the update.

Any help would be highly appreciated. (Also, if possible, a link to download a previous service release.)

Im also having the same issue in:
Version 8 SR29
(8.29.26063.11001, 2026-03-04)

I only have the local installers until 8.29, so i cant backtrack and test in which release the function broke.
