Camera BG jitter offset (regression) #91398

Closed

System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.63

Blender Version
Broken: version: 2.93.4, branch: master, commit date: 2021-08-31 09:23, hash: b7205031ce
Broken: 2.82
Worked: 2.81a

Probably caused by 9516921c05 (this certainly broke between ba1e9ae473 & da6929488a)

Short description of error
Camera background jitters on large scene offsets.
bug_report_camera-bg-jitter-offset.zip

Exact steps for others to reproduce the error
To see the bug:

  • Unzip and open the file [bug_camera-bg-jitter-offset_v001.blend]
  • Select [SceneNode] in the [tracked_cam] collection, make sure Viewport Shading is in Material Preview-mode.
  • Click "Play Animation" in the timeline.
  • Look below in the Graph Editor. I have tracked a camera in another softwaware, imported it by FBX into Blender. Here to show the bug I have the tracked camera and its parent at origo and then at frame 300 I offset it all to x 100'000 by y 5'000 units. This to show the obvious jitter of the camera background at this extreme location.
  • Happily, this does not affect the actual camera position, as I first thought. But it does affect the viewport renders, making it useless for previews on large scenes, like landscapes.
  • Now you can switch between Material Preview and Rendered View and scrub the timeline to see the difference too.

Very best regards to all people in the team and greetings from Stockholm, Sweden,

Can confirm, this wasnt shaky in 2.81a, will try to find the culprit commit.
