Short description of error
Blender crashes on every single time using trackpad pinch (zoom) in Node Editor.
Using zoom function through view>zoom in/out works fine.
Once in a while when trackpad pinch does not crash blender, the node editor will turn blank and all function in Node Editor cease to function. (probably stuck zoomed in at the bottom right of the screen [see scroll bar in screen shot])
The only way I found to fix it is to reload the UI.
Trackpad pinching(zoom) in sidebar causes it to be stuck in either too big/too small unable to get to a size in between.
