--- Comment #4 from Andreas H <andreas.harat...@gmail.com> ---
Git commit 6c9026628cdbfd38baeeceb48e672c5458e93f8e by Andreas Haratzis.
Committed on 08/07/2020 at 01:33.
Pushed by apol into branch 'master'.
Fix DrmOutput sometimes being freed with a pending pageflip, often when waking
from sleep.
It is possible for updateOutputs to be called when a pageflip is pending.
Freeing a DrmOutput with a pending pageflip is not allowed (see ~DrmOutput
assert - the page flip handler will be called on the freed memory, possibly
leading to use-after-free).
This works around the problem by delaying the destruction with teardown().
