On Windows 7. Have seen this, but never thought that it could be a
bug. Mostly restart the project from scratch, assuming it to be a
problem with a control point or two. Impression I had, but never
actively followed up on, is that two images are connected with a
faulty control point and that hugin attempts to bridge them via the
spokes that are criss-crossing the field.

I also use 2012 and 2013 interchangeably, so not able to pin it on a
specific version. 

Will attempt to reproduce if I see it again.

No. I know, I should have. Maybe someone else did... No, I just checked and
couldn't find anything. I could enter a bug, but I currently don't have any
pto file to show the issue, so it would be useless. I'll do it next time it
happens, if no one beats me to it.

I am almost sure that some (most?) optimization results will never trigger
this bug, so that re-optimizing quite probably was why the issue
disappeared. I always use the "progressive" optimization technique (where
you first optimize by positions, then by positions-and-view and so on and I
often noticed that when this bug appeared, I could avoid it by resetting
all optimization parameters and then stopping at the last step which did
not trigger the bug. So my workflow when seeing this issue would be:
- use one optimization level
- check in the preview if the bug does not appear
- use the next optimization level
...
- if the bug appears, undo the last optimization.

I've tried to quit and restart the app, even boosting the image cache 
memory to 2048 when I did it. No luck.

Now, I just added some more control points and re-optimized and all is 
well. Not sure those steps had anything to do with it though.

I sometimes get this too on Windows. I may be wrong, but I recently managed
to get the preview correctly by just closing Hugin and then loading it
again. But I think (I did not pay much attention) that sometimes this did
not work.
