Close all apps besides safari, then open Safari and close all tabs so the browser just shows a blank page. Exit out by clicking the home button once. Then double click home to show your open apps, which should just be safari; the preview image should show a blank safari page, and if you click on the window with the safari app you should enter the browser and see no old web page flash, just the blank page. Exit by clicking home once, rotate the ipad 90 degrees, then repeat the exact same process- click home twice to bring up a preview window and then enter safari to see if it is the blank page or if safari is using an old cached image. If any orientation has an old page pop up, make sure to enter safari in that orientation and clear out the page. Once you have done this in all 4 orientations you should be fine. What a pain, right? And you have to do this whenever you want to clear out old safari images. It has worked for several weeks for me with the problem recurring, curious to know if this trick works for others as well. But seriously apple needs to just fix it on their end to avoid this hassle.
