Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-04-09 23:42, hash:
0a460d470718
Worked: 3.5
Caused by
7a267aa000
Short description of error
When using the
paint.sample_color
operator via the shortcutS
, it will crash Blender. If there is not UV map present, it will not crash.Exact steps for others to reproduce the error
S
to color pick any surfaceWhen following the above instructions I get an exception in
drw_command_create
. That function is called with the DRWShadingGroup *shgroup argument uninitiated.Immediately before this we go through new code recently added to
select_cache_populate
, added in7a267aa000
from PR #105498 on April 8th.If I had to guess I would say the new section is testing if the object is in edit mode, and if not assuming it is in object mode and only doing some shader initiation if in OB_SOLID mode, returning early if not. Since I am in neither object mode or edit mode some initialization is not done and we crash.

Setting higher priority because this looks to be something that would cause similar issues far outside of the reported problem.
