My understanding of how the QML cache works is that if a QML file has
changed, the app’s cache is invalidated and regenerated. If this doesn’t
work, this is a bug in the cache mechanism itself. That said, with the
latest image upgrade, webbrowser-app and webapp-container didn’t change
(there was one change merged, but it only touched the autopilot tests).
What changed is the version of oxide (from 1.2.5 to 1.3.4), but oxide is
pure C++, there’s no raw QML involved, so I don’t see how the cache
could possibly be impacted by this change. Unless I misunderstand how
the cache works.

Title:
  QML cache not regenerated correctly on image update

Status in “android” package in Ubuntu:
  Invalid
Status in “lxc-android-config” package in Ubuntu:
  Confirmed
Status in “lxc-android-config” package in Ubuntu RTM:
  Confirmed

Bug description:
  image rtm-proposed 166

  Multiple problems here, due to the fact that oxide was updated (a new
  release) and webrowser-app was updated

  1) webbrowser-app cache was not updated on the image upgrade in .cache/QML/Apps/webbrowser-app and 
  desktop versions of web pages are displayed until the cache is destroyed or regenerated. Try cnn.com or nytimes.com

  2) no webbapps cache is regenerated, so launching of the webapps
  displays wrong pages (.cache/QML/Apps/*webapps*) due to stale cache.
  You can try Google Maps for an example. Deleting the cache makes them
  work again properly.

  Expected Results:
  - after image upgrade, either all of the apps should be regenerated smartly, or we should blow away all of the caches to prevent an issue when a library (like oxide) is upgraded and causes an invalid cache.
