Open GL fail in section viewports with source rotated

[grant_PD]

I spent a long time the other day troubleshooting this bug:

I made a master groundplan on a sheet layer, and had it rotated 90 to fit a landscape page.  

I went through the entire groundplan and cut sections for elevations, putting the elevations on a separate page, using the "create section viewport command."

My standard rendering style for elevations these days is OpenGL, with a high ambient light setting and ambient occlusion, with hidden line over the top (background render).  This gives a washed out color elevation with crisp lines.  

Not a single elevation worked.  They all tried to render, then failed, just showing the hidden line.  If I turned off the hidden line, I got ONLY the cut plane.  A custom renderworks setting would work, but that's far too time consuming.  

After turning off various things, I went back and un-rotated the master plan so that it was in its original orientation.  Everything worked just fine after that.

I use the same style in my work.

I haven't seen this exact issue but I have seen issues with OpenGL / Hidden Line rendered viewports when the Sheet Layer viewport itself is rotated. It only works properly in 90 degree increments. I wonder if these issues are related.
