My nvidia-settings control panel shows the color correction curves for red,
green, and blue, along with a gamma setting of 1.0. When the problem occurs,
those curves get flattened into a single straight line, and gamma remains the
same. I think that means it's not just a gamma problem.

Possibly worth noting: Older versions of wine (I think version 1.7.15 is an
example) did this only at certain predictable points while playing Guild Wars
2. It happened when the launcher ran and when entering a new zone in the game.
If I manually re-installed my color profile, it would stick until one of those
transitions happened again, even if I switched to another virtual desktop in
xfce and back to the game. In wine 1.7.45, it also kills my color profile
whenever I switch back to the game's virtual desktop.
