Recently I've noticed a regular memory leak issue with the animated wallpapers, in particular with BlueNight.

I'm used to leaving opera windows on speed dial when I'm not actively using them, and I noticed that, while doing other stuff in the computer, I would get those random slow downs. Upon checking task manager, my memory usage skyrocketed to nearly 100% for no apparent reason. Upon closer inspection, it is always a hanging speed dial page that keeps pulling memory until all of them are used.

The problem is completely gone swapping to a static wallpaper, so the animation might likely be the issue here. Is anyone having the same issues? I'd like to keep using the animated ones, but not really at this cost!
