<div>
<pre>The current usage of the Wayland dispatching API is not conducive to
multi-threaded usage and as a result, using Wayland from multiple threads can
lead to deadlocks. e.g. GStreamer and/or EGL usage off the main thread will hit
Wayland from multiple threads.
>From the Wayland man pages, the solution is to use the
wl_display_prepare_read(), wl_display_read_events() and
wl_display_cancel_read() family of functions.</pre>
