Research direction

Start by running an ERRC test with BDs on Windows 11 and watch the LDC, BIS, and read-rate plots for the intermittent compression and jumps. Enable verbose mode in File>Preferences>Common, reproduce the glitch if possible, and save the Console logs; done means identifying and correcting the cause so the plots remain normal.

Description

Describe the bug
A clear and concise description of what the bug is.

ERRC produces janked results from time to time.
In the middle of a ERRC test, LDC and BIS goes way up, graph changes intermittently from fine to everything compressed to the left when moving the cursor.
See screenshot. I stopped the test after observing a glitch. Read rate curve also goes twisted.

To Reproduce

Happens when performing ERRC tests w/ BDs. Ran into this from time to time. No idea what causes a stable reproduction.

Logs
If the issue is linked to reading/scanning a disc, toggle verbose mode in File>Preferences>Common, reproduce the problem, then go over to the "Console" tab, save the logs to a file, and attach them to this bug report.

I checked it now and will upload it next time, but I can't make a good reproduce so forgive me for now.

Desktop (please complete the following information):

  • OS: Windows 11
  • Program version 0.8.1 pl8

    Had this w/ a self burned ame BD-R QL, maybe not disc related.
