Okay, Chris. I took your advice from the Kineme "use bugs to get girls" (ha) thread and pared down my example. Can't see any reason you would not be able to open this one is 10.5, but what do I know -- this test version is a gaussian gradient in a render in image patch to a crop patch to a billboard.
The main issue: does the viewer look the same in fullscreen mode (ie, same size, same placement)? At first I thought that bypassing crop = yes. With crop = no. Now with my stripped down comp the billboard seems to be having other problems. Using a gaussian gradient plugged directly into the billboard produces sometimes image, most of the time black. This is different behavior from the (very) different size/placement issue I was originally chasing. I have to come back to this later. It's getting worse...

I started off with the Anchor Position patch and it was working as expected then. Now it does not seem to have an effect when inserted. Using a Rendering Dest Dimensions patch throughout. Currently Width/Height plugged into a Billboard set to custom, but tried Billboard set to Auto Height and sending through a Render in Image (with Billboard, Sprite), too. >> - Another related scenario is trying to set up QC to play various >> media (for >> ex., playing successive videos in PAL, NTSC, 720p) and appear >> properly on >> screen using a video projector (like QuickTime Player can do).

And I have no access to CL, of course.
