the best way to wake it up from within the backend? I tried: wl_event_loop_dispatch(loop, 0); and this works - just not sure if it is the right way to do it (ran into segfault after a short time, not sure if its related...), and feels more like a workaround

Hi,<br>
<br>
have you checked at what time you call the notify_*() functions? Are<br>
they called the 10 seconds before or are they already delayed?<br>
<br>
Sounds like you might have issues with the compositor event loop, maybe<br>
not servicing your extra event sources in a timely manner. I assume you<br>
are aware that the compositor main event loop does not spin regularly,<br>
it only spins if any event source is ready. Therefore it may sleep for<br>
arbitrarily long times, and clients sending requests can wake it up<br>
which would explain why extra apps can work around it.<br>
<br>
<br>
Thanks,<br>
