I would like to know if this issue has been resolved. I have read past forums related to this topic but with older versions of Twenty Eleven. I noticed that it is severe in IE 10. No problems with Firefox. I wish IE would behave the same way. Here is my website so you can see for yourself what is doing:
Click trough each menu tab to see it.
Before, I had a solid image background and when I tried to use a full image background the problem began; or perhaps not noticeable. Here is the code I borrowed from another site:
background: url(images/bg.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; }
The size of the jpeg image I am using for the background is 777kb. Is this too big? I tried copy and pasting the code from Firebug, which is slightly different, but the flashing was still there.
I am using the Twenty Eleven child theme to make these changes.
