Blue pigment over flash movies (Youtube for example)
some flash movies on sites like Youtube have a blue tint. Apparently it is due to Flash and possibly the use of VDPAU.
This is not a LMCE defect but a general issue. it is described:

but the following fixes it:
cd /usr/lib/flashplugin-installer || cd /usr/lib/adobe-flashplugin/
sudo perl -pi.bak -e 's/libvdpau/lixvdpau/g' libflashplayer.so
