This is more an UI inconsistency report than a bug.
I discussed it with Matias Mendiola (mendio) and suggested to report it to William Reynish (billreynish) or Antonio Vasquez (antoniov).
Operating system: Windows-10 64 Bits
Graphics card: GeForce GTX 1050
Broken: version: 2.80 (sub 74), branch: blender2.7, commit date: 2019-06-12 18:00, hash: rB2404220e80a9
Short description of error
- The icon used for Object Data (green in default theme) in Properties tab and Outliner are different. One is a stroke the other a pencil.
- In the outliner, clicking on the Object Data (green icon or the name) toggle the edit mode. In edit mode, the green icon is surrounded by a rounded rectangle for all objects (meshes, curves, surf, MBall, text) except Grease Pencil objects.
- Again in outliner, choosing the layers of a Grease Pencil object (green pencil icon instead of the dot) activates it instantly in other editors (3D view, Dope Sheet, etc.) except in the Properties editor where we must hover above the editor for the change of layer to happen.
Exact steps for others to reproduce the error
Open Blender with default settings.
Go to the 2D Animation Workspace.
Go to Outliner and Object Data tab in Properties editors to find points mentionned above.
