Whenever I load my Flex 4.5.1 application the background flashes white before the app loads.
Looking around the web, the only fix I've found that works in Flex 4 is to set my wmode to transparent.
I would like to not have that sort of performance hit just to get rid of a flash of white at the loading of the app.
I went in to the html.template and changed everything (flashvars, body tag, body style, object tags, object tag params, to black as some of have suggested. Though the one remaining thing I haven't figured out is how to set "bgcolor='black'" on the embed object now that it's created by script.
Is there a solution to this that doesn't involve setting wmode = transparent?
