There is definitely at least one bug somewhere in the fast preview, and narrowing it down is the challenge.
I've been able to trigger a crash by playing intensively with the widgets on the fast preview. Not the kind of activity that would happen in the course of normal use, but definitely pointing to a robustness problem, maybe a memory leak. I simply switched randomly between projections and moved the FOV sliders. Over time the grid texture deteriorated visually. Then it crashed. Tried within gdb but got no stack trace. Probably other textures are affected as well. I only saw the grid texture because I modified it to display a specific simplified pattern without transparency to exclude the grid generation as source of the error. The grid anyway does not display properly (see bug 804800 which may be another symptom of the same bug). I suspect the bug was introduced with the last major work on the fast preview, the introduction of the overview pane in 2011.0. We need to isolate it from other factors (e.g. drivers/video card) and find a way to (ideally) consistently reproduce it. ** Summary changed: - Hugin Hangs when Fast Preview Used + Fast Preview Hangs or Crashes since 2011.0 ** Tags added: fastpreview -- You received this bug notification because you are a member of Hugin Bug Hunters, which is subscribed to Hugin. https://bugs.launchpad.net/bugs/792896 Title: Fast Preview Hangs or Crashes since 2011.0 Status in Hugin - Panorama Tools GUI: Confirmed Bug description: Upgraded from 2010.4 to 2011.0.0 and it has hung 3 times in about 15 sessions.
