The problem appears to be in the update loop. It's not clear what triggers this issue.

txoof commented 1 month ago

The trigger appears to be a crashed plugin; the main update loop does not see this as a stalled plugin and continues to try to display it.

txoof commented 1 hour ago

Re-opening this as something is causing all plugins to return invalid images after a few hours under some (??) circumstances.
