I'm running the latest desktop sync client (2.2.4) on Ubuntu 16.04 and I would like to understand more about the location of the monochrome icons displayed in the status menu.
Typically applications store these in
/usr/share/icons/hicolor/, and I see many ownCloud icons there, but no monochrome ones.
If I try
gdbus call --session --dest com.canonical.indicator.application --object-path /com/canonical/indicator/application/service --method com.canonical.indicator.application.service.GetApplication
I get the location
/tmp/iconcache-nfcjVp which has the monochrome icons.
Since /tmp/ is temporary, I'd like to understand what process is creating these monochrome icons and storing them in /tmp/. Can anyone please explain? Ultimately I would like to create custom icons and use them, but this is not possible for items which only exist in /tmp/ obviously.
