QuickTime for MAC display error——changing color while playing when fullscreen

And whenever i move the mouse or pause anyway to unhide the interface ,it will change to the right color .Any other players like vlc,mxplayer running the same files never have a problem like that.

important：the files i check are MP4 with quality lower than 1080p .That means I haven't found any problem with MP4 files in 1080p

So this is a problem ，and only happens on QuickTime .Other players are doing well but they are hungry for batteries,so please help.I can’t be more grateful for everything you'll do for us.
