Settings lag, typing lag, unlock lag

[jinjuice]

After the 4.4 update, typing has gone laggy. This can especially be seen while swipe typing and just even typing here (on my experia z).
The scrolling in settings also lag.
When I unlock my phone, a black screen appears for a split second before my background appears. (from lock screen to background).

Apologies if this isn't the right place to post.

I just discovered that the black screen between lock screen and xperia home is caused by the wallpaper used... When I use 'xperia wallpaper' from live wallpapers I don't experience any black screen

Same problem here. Xperia ZL 6503, Kitkat 4.4.4 build .283.

The whole system is laggy, and I have to wait to the keyboard when I write. I apply the "fix" mentioned before, and the behaviour is better now (except for the keyboard).

When I call the task list and close every running task, the whole behaviour is faster.
