I'm currently using Spine to create cutscenes, and I have a bounding box to represent the visible part of the scene, so I can properly scale and position the skeleton according to the user's screen size.
The problem is this bounding box has a different size in runtime than how I set it in Spine itself. I also used Skeleton Viewer to be sure the exported JSON was OK. Check the images below:
Scene in Spine:

Scene in Skeleton Viewer:

Scene in the game:

The bounding box in the game was rendered by using SkeletonRenderedDebug.
I'm using the latest version of Spine (2.1.27 Essential) along with the LibGDX runtime from Github, up to commit aa4a8d0 (Fixed setup pose slot blend mode.).
Thanks for the attention.
