still not seen a debug log (wiki)
but you could try the new beta's and see if you still got this issue.

I have these settings set in the latest Kodi v10 64-bit, but all of a sudden clean library dialog box messages are constantly appearing during playback.

How can I disable these now?

How can I disable these now?

Look at the setting of System / Media / Library / Update library on startup.
If it is already disabled, then you have some other add-on installed that is yanking and triggering the library update process.

Yes, I run the watchdog service. I need to check why my music library scan does not complete properly and basically continuously runs.

I've encountered a recurring issue that may have started after I installed the Library watchdog addon. Unfortunately, even after I removed the addon, the problem persisted. I followed the recommended solution and made the changes to my advancedsettings.xml file, but it didn't resolve the issue:

xml:
<advancedsettings>

  <videolibrary>

    <backgroundupdate>true</backgroundupdate>

  </videolibrary> <videoscanner>

    <ignoreerrors>true</ignoreerrors>

  </videoscanner>

</advancedsettings> 

I then tried reinstalling the addon and adjusted the settings to increase the polling interval, but I still couldn't fully disable its effect after uninstalling it. My suspicion is that the addon has made permanent changes to Kodi's default settings that aren't undone by uninstalling it.

I also attempted to clear the cache and rebooted my Shield, but with no success. Any suggestions would be greatly appreciated!
