Flash video appears blue
I am having an issue in my ubuntu 11.10 , with youtube colours being messed up - it looks as though channels have been muddled like RGB -> BGR or something. How can I fix it?
edit: it does not happen in html5 version, only in flash player. however, some youtube videos can not be watched in html5 (e.g. ones with ads), so it is still a problem often
