CyanogenMod 7 for Milestone A853 RC12 July 14 version was released, usually it contains important fix, for there is only 3 days after the previous update was out, so Nadlabak fixed the touch driver and bring us the 5 point touch feature, it is so cool for before days we only have 4 point touch on Milestone A853.
I have download and have a test with the New update, but unfortunately I expected a little higher with the new touch driver, when the phone reboot after installation of the RC12, I can feel obviously lag when I am scrolling everything, even the launcher pro and opera mini, the graphics will move with my finger after 0.5 second, for definite this , I have rollback to CM 7 RC 11, my Milestone work with no lag again.
I remembered the lag scrolling appear on the Android 2.2 using the 2.1 kernel roms, but not so heavy, I should see whether other people also have this issue.
Maybe that the new Interactive governor affect the system, anyway a new RC12 is under construction, will be rollout tomorrow, just wait for while.
