screen display bug

I don't know how to post a picture but i found that suddenly my screen shifted by half a screen. If anyone tells me how to post my screenshot i'll show it.

I've had this happen a few times too, just never thought to mention it for some reason. I've got a droid razr m running andriod 4.1.2 Managed to figure out how to reproduce this: Go to the item screen for any tower, click equip/drop, then quickly click cancel before it slides off screen. Works every time for me.

Thanks for reporting, I filed a ticket for it!
