video driver: xserver-xorg-video-intel
OS: debian 9 (testing)

reproduce: play any movie, and move mouse to player window.
reproducibility: 100%

I just git pull mpv, and rebuild.
and git update to: 4ce5302..9ca1592

[zhangn1985]

checkout to 4ce5302 , and rebuild, everything goes fine.

Bug is caused by an (unintended) change in behavior to subtitle color management. I'm thinking it might be time to revisit this behavior, since pass_colormanage has grown to be much more than a simple routine for adapting colors (and more of a big auto-detection heuristic function).
