System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 526.98

Blender Version
Broken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: rB55485cb379f7
Worked: (newest version of Blender that worked as expected)

Short description of error
When I'm using lineart with bound cameras on the timeline and View Lock, Camera to view is True, sometimes the lineart updates dynamically, sometimes I have to click the Clear Baked Line Art button to force an update in the viewport.

Exact steps for others to reproduce the error

Open the attached file.
Clear the baked line art. Do not try to bake.
Keep "Camera to View" set on. (Note that in frame 1, lineart is updated as you navigate through the view)
Step through each of the 3 frames, and rotate the view with middle-mouse-drag.

Only one of the frame/camera will properly update the lineart. As the viewport moves to the rear of the cube in the other two, the lines are missing. I haven't found an obvious reason why one frame is working, or why that frame. The working one has been 1 or 2 just while I wrote this report.

Clicking Clear Baked Line Art again will update the cureent viewport so it is correct, but rotating the view will again show one camera binding working, the other two not. It does not seem to matter which frame is active when the Clear Baked Line Art is clicked.

I can't replicate, or I misunderstood the problem.

Clear the baked line art. Do not try to bake.

The file already has the Lineart cleared

Step through each of the 3 frames, and rotate the cube with middle-mouse-drag.

In fact, the Lineart is not updated while we rotate the view (which I believe is for performance reasons), but right after changing the frame, it is updated.

Please give us more clear instructions on how to reproduce the problem.

Yeah, 2 was somewhat redundant, but crucial, so I added it as precautionary. It doesn't affect the outcome, provided you have just opened the file.

So I doubt Blender want big video files uploading here, so I captured the behaviour and posted to YouTube to show what I mean. Hopefully it is self-explantary given the above description. Frame 1 updates while dragging, frame 2 and 3 do not update.

Thanks for the update. Now I can see the problem.
In fact in frame 1 the Lineart is updated confirming the camera position.
On the other frames, the camera used to update the Lineart appears to be wrong.
