System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 550 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 376.54

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-06-05 12:32, hash: a6cd77bad1
Worked: 02.06.2020 build hash: cecda64e2e

Short description of error
In the latest versions, one of the bones in the attached file has disappeared.
This is because the object used to view it has become invisible.

File where the bug was identified:
girl_bug.blend

Exact steps for others to reproduce the error
Open the bone_w_loose_edge_obj_bug.blend file in the latest master notice that FK_forearm.L is missing in pose mode and object mode.
Open the same file in the 02.06.2020 build and the bone should be there.

Simplified file revealing the bug:
bone_w_loose_edge_obj_bug.blend

The bone is invisible because the object related to it is invisible. And it looks like a bug.
I will update the description.

Germano Cavalcante changed title from ~~Bone had disappeared in pose mode and object mode~~ to Lose edges of objects used for bone visualization are sometimes invisible

@mano-wii Thanks for simplifying the file. Now with your posted file i can crash Blender if i click the TAB-key, about less then 4 times. It seems like you have exposed more problems

D7962: Fix #77342: Fail to draw loose edges seems to fix it partly.

I have a possible area to look at. Overlay_armature calls drw_batch_cache_generate_requested directly. this creates a second instance of batch extraction tasks and it won't be completed as it used to be.

/* TODO(fclem) needs to be moved elsewhere. */
  drw_batch_cache_generate_requested(custom);

might get in our way and we should move it somewhere else. Removing these fixes the issue for small files. larger files crash as the batches aren't up to date.
