Hey.

Probably the following has nothing to do with this bug (which I'm also experiencing in at least Evolution):


Could it be that this issue is somehow caused by a kernel change (specifically something that happened in kernels >5.2)?


I see this pattern of fast:
pid 243332] recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)
[pid 243332] poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}], 2, 17) = 0 (Timeout)

in quite a number of applications (e.g. diodon is one: https://bugs.launchpad.net/diodon/+bug/1871008 ... and I've also noticed it in cinnamon https://github.com/linuxmint/cinnamon/issues/9085#issuecomment-615543487 )

These in turn are all programs which might play a part in a bigger issue I suffer since kernels >5.2, namely some massive increase of CPU temperature respectively power consumption for GPU but also non-GPU intensive workloads:
see:
https://bugzilla.kernel.org/show_bug.cgi?id=207245
(with links to other related bug reports)
for more details.



Cheers,
Chris.
