Title:
SessionMediator locks mutexes in one thread and unlocks them in
another
Status in Mir:
In Progress
Status in mir package in Ubuntu:
New
Bug description:
SessionMediator locks mutexes in one thread and unlocks them in
another thread during create_surface or exchange_buffer. This can
cause undefined behavior:
http://www.cplusplus.com/reference/mutex/mutex/unlock/
"If the mutex is not currently locked by the calling thread, it causes
undefined behavior."
This may potentially be the root cause of a hang (wait handle never
signals) seen when creating/destroying menu surfaces while a parent
does swap_buffers.
