this is the first time I saw this, when I started up my mac, I see all the icons along the top, time,battery, etc, but they do not have the highlighted bar through them, I have it set to a translucent setting. But when I opened finder, it went right back to normal instantly. I even shut down & restarted the mac to be sure, & all was normal/OK. Is this serious? do I need to be concerned? I have been doing graphics stuff, encoding .mov files to mpg2 in roxio toast. while doing video encoding I notice n up in the top toolbar, for the video card being used. I have gfx card status installed. Do I need an update? I am running 10.6.3. I have had the mac since mid June 2010, & it runs good. I hope this does not mean my graphics card is failing, I live quite away from an apple store.
