Libcosmic applications can sometimes "lockup" which causes it to hang for 30s or so

[Quackdoc]

This happens with at least cosmic-files and cosmic-settings, but I find it hard to reliably replicate with cosmic settings.

the line where it starts to spam [2024-11-01T07:39:59Z WARN iced_futures::subscription::tracker] Error sending event to subscription: TrySendError { kind: Full } is done immediately after cosmic-files starts to respond again

with cosmic files this is the output to std. Nothing else related to the issue is shown even if you use RUST_LOG=debug using trace is far to verbose for me to actually copy anything and make sure nothing private is being shown, but if it will be helpful, I can grab it and try to redact anything private
