So occasionally safari does this thing where it will load a page, but not display it. Rather a grey gradient with its opacity lowered is shown (see image below). Anyone have any idea why safari does this? Reloading the page doesn't work, and I have to either close the tab or quite safari and then reopen the web page for it to return to normal.
I don't use Safari so can't really comment, but there seem to be a decent number of results just googling "safari grey page".
