CAIRO_STATUS_SURFACE_FINISHED error in githubnotifications

[ervinpopescu]

I get this annoying error in my logs and I can't seem to figure out why:

Seems to happen randomly, doesn't seem to be reload-related, doesn't look like it's related to polling.

Maybe it's some of the finalization code written recently?

Not sure how I missed this...

Do you reload your config regularly? That could trigger finalisation of surfaces etc.

I don't reload that often lately. Something like once a day max. That said, I do think it is reload related after all. I just reloaded a second machine I don't reload that often and the error occurred again.

To me, it looks like more of an issue with a qtile which is not reloaded that often.
