Description

Edit by @Alaska (Alaska)
Bisecting points to rBa1f9eebc0b5f as the cause.

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.92

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-06-02 22:21, hash: rB2e52b3206cc6
Worked: 2.83.0

Short description of error
The outline of a selected object is not shown.

Exact steps for others to reproduce the error

  1. Create a new scene.
  2. Give the default cube a sub-division surface modifier with a high setting (I used 5).
  3. Apply the modifier.
  4. Select everything in the scene and duplicate it a bunch of times.
  5. At a certain point (roughly 500 objects or more), some of the "cubes" will not produce a outline when selected.

Original steps:

Open a blender sample file like the tree creature. (Can be downloaded from here: https://www.blender.org/download/demo-files/)
Try to select something. Make sure that "Show Overlays" and "Outline Selected" is on.
No outline is drawn around the selected object.
Isolate the selected object with "/". The object is shown with an outline.

I made two screenshots from my project one with blender 2.90 alpha where the selected object is not highlighted


and one with blender 2.83 where the selection outline works.

I am able to reproduce the issue on Linux with Blender 2.90.0 rBb94ab93dfb82 (2020-06-03 18:45) and 2.90.0 )rBe723ec04fb61 (2020-06-04 03:23using the tree creature file.

I believe I have also found steps to reproduce this issue from scratch. However, Blender keeps frequently when I try to do this so I'm not sure if the steps I list are actually capable of reproducing the issue.

  1. Create a new scene.
  2. Give the default cube a sub-division surface modifier with a high setting (I used 5).
  3. Apply the modifer.
  4. Select everything in the scene and duplicate it a bunch of times.
  5. At a certain point (roughly 500 objects in an initial test), selecting one of the "cubes" will not produce a outline.

I will add this information to the description of the task. I will also attempt to bisect the cause, may take a while.
