Description
I see several bugs against various linux distros about the video corruption problem that appeared on intel graphics when the 3.14 kernel arrived, but I don't see an upstream bug here, so I'm making this one. Details of the problem can be found in various other bug reports:

Only seems to affect "xv" video, gl rendering is OK (and a good work around), but xv seems to be the default for most players, so it gets noticed.
