Ads on android tablet..wandering black boxes

[665TheNeighbourOfTheBeast]

You seem to have some kind of new protocol for ads on the mobile site that is making it jump
Giving wandering black boxes
"Flashing " black rectangles at random places on the screen
And occasional random jumps To a black screen with an ad in the middle
On Kitkat

Hullo 665 (fantastic username btw)

Sorry to hear you're having box issues.

Anyone else having this problem?

I sometimes have this issue, but not at the moment.
