Intel VAAPI howto with Leia v18 nightly based on Ubuntu 18.04 server
Not strange at all. You can't go back to or load an incompatible skin that doesn't have support for DialogConfirm.xml - without this support Kodi can't show the dialog "Are you sure you want to keep this skin?" while using the new skin. Kodi can't even notify you of the failure if the skin doesn't support DialogNotification.xml (pre-xbmc.gui API 5.11.0 skins will not support either XML).

Due to the DialogConfirm.xml failure your original skin, Confluence, is reloaded.
