SGS2 miui problem

Dec 20, 2011
I found onething.
strangly sgs2's miui is slower and slower as time goes on.
i guess, it is relate to capture function.
when i execute this function its all animation effect was slower than before.
and it allowed some of errors (like no response)
i checked it other device but they didn't (nexus one, nexus s)
so could you check it and fix it?
plz :D

if you can't understand this problem.
i'll show you :D
(i checked it the latest version and 1.11.14 but it has same problem)

ps. miui music app was fantastic!
it's user equalizer was best! any other app
