I noticed there's a vdpau 0.6 (12.3 ships 0.5), released Feb 1 of this year so I tried it out by rebuilding the src rpm from openSUSE Factory and and I'm not seeing any blue tinting. Tested using 2 different browsers (Opera and Rekonq)

as far I can tell I've no mms.cfg files anywhere, that workaround caused nothing but crashes for me

Can anyone confirm this?
