Hi,

have you checked at what time you call the notify_*() functions? Are
they called the 10 seconds before or are they already delayed?

Sounds like you might have issues with the compositor event loop, maybe
not servicing your extra event sources in a timely manner. I assume you
are aware that the compositor main event loop does not spin regularly,
it only spins if any event source is ready. Therefore it may sleep for
arbitrarily long times, and clients sending requests can wake it up
which would explain why extra apps can work around it.


Thanks,
