I know there is the Sticky thread on Bug/defect checklist but to me that thread is way too long and I'm not going to read through to see if someone has had a similar issue to me. I tried using the forum search but can't really tell if anyone else has this issue. Basically occasionally when I scroll through the start screen a live tile will flash red for the slightest of moments as it appears if it wasn't on the screen. I'm fairly certain it has only happened on the Facebook tile which I have at the small size and also the WP Central tile which I have at a medium size. Funnily enough both tiles are blue. It doesn't happen often but has happened enough for me to see it happen quite a few times. Anyone else seen this? I'm thinking this is more of a software issue than hardware so not going to bother returning the phone and hope a software fix fixes it. Doesn't annoy at all but still though I'd post this to see if it's a common thing. [h=3][/h]
