UV Local View: Cannot select anything in the UV editor, will crash with 'grab' 'relax' and 'pinch'

Description

System Information
Operating system: W10 v1903 (Build 18362.387)
Graphics card: Nvidia GTX 1070 Max-Q

Blender Version
Broken: 2.80

In a new Blender project this works seamlessly, but in the one I am working on right now I want to create some grass blades. Unfortunately I cannot select any vertices edges or faces that show up in the UV editor. Upon using either grab, relax or pinch, Blender will just close.

Open "UV Editing" tab, select one of the grass meshes, go to edit mode, try to select the vertices. Rest goes as described above.

This is tied to the image being pinned [will need to figure that behavior out]
Will take care of the crashes.

Correction: this is tied to UV editor > View > UV Local View being enabled.
(Wasnt aware of this thing, but) In this mode, only the faces with the currently selected image texture node associated should be displayed.
But apparently 2.8 does not respect this and shows all (but not all are selectable -- because the selection code apparently checks for this).
Will take care of that [not showing these in the first place should also take care of the crashes].

Eeh, this seems a bit like a rabbithole, needs more investigation.

  • draw_uvs_texpaint respects UV_SHOW_SAME_IMAGE actually, but draw_uvs doesnt (and doing it there seems excessive -- but probably the only way to do it)
  • 2.79 also seemed to only do it in texturepaint mode? (looks like with this setting ON it never displayed any UVs in editmode...)

Thank you very much for clarifying!
