So it's a bug in mesa then?
My distro is at 11.0.4 atm, if I'm about to ask for a fix, what's the

proper fix?

This looks like an application bug to me - here's what the game does with the
minimap fog of war in the apitrace (right at the start of each frame, so it's
easy to find):
1. Uploads the fog of war to

This issue also happens on radeonsi, with Mesa 11.1.0-devel (git-d6fbcf6).
According to POE forums, it used to happen on catalyst too at some point, but
it has been fixed since.
My card is R9 280.
