Sorry for my late reply but my ISP is having issues since Friday.
Thanks a lot for your help - strangely this helps in my preview panel where the currently selected unit is shown but not when I use the exact same code (using the same method where I initialize the SkeletonGraphic, set the scaling mode etc.) for the list of selectable units. For these, my Spine animations are scaled down to a tiny size rather than filling the available rect.
In my quest to find the issue or at least a workaround, I eventually tried to just DestroyImmediate the SkeletonGraphic component and add a new one. So far, this seems to work.
I've attached a screenshot and it seems the rectTransform is correct but the scaling of the mesh is wrong.
What I noticed is, if I do not set the sizeDelta to zero, the visual scaling is correct but only because the rectTransform is huge and, as a result, the selected unit is way to big.
Finally, if I call MatchRectTransformWithBounds before and after setting layoutScaleMode to FitInParent, it works for in both cases.
Any further idea what may go wrong when reusing the existing one?
I can use either workaround but I'd feel more comfortable to know if there might be an issue on my side or if this is caused by the issue you tracked, so will eventually be fixed.
Thanks a lot
