Hello, I saw that Mesa 18.3.6-2 was accepted into unstable on 2019-05-11. That version still hasn't migrated to testing because of the freeze. Could you please contact the release team to get this release in testing ASAP as I (and probably other users) am still experiencing this issue and it is very critical because opening a media file can cause my DE to crash causing the loss of any unsaved work.
