<br>I can not say this for sure but try the latest SVN I used to have lots of problems with the OSD like you are describing but on the latest version it doesn't seem to be nearly as bad. There is still slight shake on startup and fade but 95% it is solid. I still do notice a problem with solid horizontal lines being shaky but nothing that I can't live with.
