Over time the images become more and more pixelated. The artefacts become coarser and coarser.

The instructions are here... debug log (wiki)

If you are using the Basic Method, then ensure the following is applied...
1.Enable debugging in Settings>System Settings>Logging,
2.Restart Kodi
3.Replicate the problem.
4.Upload the log to Kodi Paste Site manually or use the Kodi Logfile Uploader. (wiki) With either method post the link to the log back here.

If you are using the Advanced Method ensure you have correctly created and applied the advancedsettings.xml file (wiki)

In both instances, you should see the word DEBUG throughout the log.

Note: Full logs only. No partial or redacted logs
Do NOT post your logs directly into the forum. Use the Kodi Paste Site. Post the link to your pasted log in the forum

My solution is to not export TV series (curtail the TV export, or leave the source off-line) but once in a blue moon, then refresh images that have degraded from the source folders. Tip: Keep more than 1 poster & fanart with the folder, which will be untouched on an export and can be retrieved if needed.

From the wiki section Import-export library (wiki) :-> 4 A Note on Artwork: The optimized image from Kodi's Artwork/Cache is exported, rather than the original full-quality image, so it is best to avoid exporting artwork if at all possible.
