Hi, thank for report, i not sure if i can reproduce this from scratch. Can you share some simple example file?

Please upload sample .blend so we can reproduce the issue. I can't deduce what is broken from provided video.

here is the edit file i'm using, the files are probably offline for you, but the strips should still exist i believe. i noticed some duration, start and end values are off the chart.

Thanks for the file. Unfortunately, I can't tell exactly how this could have happened, but I have suspicion - a possibility is, that when file is saved with newer version like 3.3, than opened and resaved in previous version, this can cause versioning to basically happen twice resulting in broken strip. see #107588

Do you have version of this file that works correctly in some blender version? I would need to reproduce strip corruption itself, to be sure.

Also I am not sure if I can fix already broken file like this. I could prevent what I suspect is happening. Possibly I can fix broken offsets by placing whole strip somewhere in timeline, but that I would hardly call a fix.

this was opened in a build from a month ago, but other odd behavior seems to kick in. i now hear all audio mixed up over the timeline.

Hello all, I have gone ahead and done some testing with this error. I have made a new bugreport (below) that helps identify the issue more clearly. I have also provided a simplified test file you can use to verify the fix.

@iss can you confirm that this bug exists on yourside?

System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.79

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-05-09 13:40, hash: d864b5ce28ee
Worked: version: 3.3.6, branch: master, commit date: 2023-04-17 14:03, hash: 948f8298b982

Short description of error
Some Strips are HIDDEN from UI but APPEAR when attempting to select other overlapping strips.

These strips are only hidden in the current Blender version. Opening the same file in blender 3.3.6 reveals all bad strips as not hidden.
