--- Comment #2 from Henri Verbeet <hverbeet at gmail.com> ---
Are you using a NVIDIA card by any chance? I've seen this happen as well, but
only ever on NVIDIA hardware. In those cases my impression was that it happens
because GetDeviceGammaRamp() (implemented with XF86VidModeGetGammaRamp() in
winex11.drv) returns incorrect information, which we then later use to restore
gamma in wined3d swapchain_cleanup(). It seems to work fine on radeon / r600g
at least.

For what it's worth, I can make something similar happen just by running
nvidia-settings.
