I recently installed CyanogenMod (nightly) on my tablet. I like it and it runs much faster than Android ever did. But when it boots, for the first 5 or so seconds, the (portrait) boot animation is stretched so that it takes up half of the screen vertically and extends to around double the width horizontally (almost like it defaults to landscape sizes or something?). After the first few seconds, it fixes itself and looks normal. Why is this happening and how can I fix it?
It's a Samsung galaxy tab 2 7.0 (p3113).
