I'm not entirely sure how to explain this but sometimes, not always, when scrolling large sections of the screen to white. It's looks like a gap where something should have popped up, except nothing is there (and nothing should be popping up. It's been happening infrequently for a couple of weeks and only on mumsnet, typically when scrolling. Any idea what could be causing this? And is it happening to anyone else?
Also, and probably unrelated, but I often have to double click when I would normally only single click. Is this just because I'm using the desktop site on a tablet?
