System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.59

Blender Version
Broken: version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560
Worked: haven't tested older versions due to the amount of work it takes.

Short description of error
Fully tracked and locked 3D trackers eventually corrupt and start jittering and moving about, and it somehow affects previous incremental saves.

Exact steps for others to reproduce the error
I have no idea of what or how it happens, all I know is that my footage is an .mp4 file, 1080p, 60 FPS and after hours of work, when adding more trackers (I have 28 in total), the old ones bug out and start jittering, even though they were tracked perfectly and were locked. This is the second time this has happened to me in a row, and for my second attempt I was saving incrementally but just noticed it doesn't matter as when this happens the whole tracking gets corrupted, even on the previous save files which makes absolutely no sense.

The footage is playing back just fine, I even replaced it with an image sequence and I can confirm that the issue is with the trackers, not the footage.

Here's a video demonstrating the issue after it happened (sorry if it's not much but I literally have nothing else to show):

I did search for similar issues and found #44675 but my issue is different because I didn't even need to reopen the file for it to happen and I still consider this a breaking a bug which shouldn't happen, considering it made me waste a minimum of 5 hours of work.

Again, I know this is not enough information but I literally have no idea of what else to say about this. I was just tracking normally and it happened.

Can you provide mp4 file and .blend file if possible?

Also please check if this happens with Blender version 3.3 - it should handle movie seeking better than previous versions assuming that is the core of the issue.

Tried it for a few hours on 3.3 and didn't see the issue occur, but I'm giving up on this project because the solved motion is unusable. I've had enough of this.

Thanks for checking.
I wasn't able to reproduce either, so assume the issue was resolved.
