EditText cropping characters while editing

I'm working on an application for Samsung Galaxy 5 with Android 2.2-update1 that has various EditText fields and I noticed that all EditText fields below the middle of the screen is not repainted correctly when the user is typing: all the characters appear chopped, leaving their half top plain white. I've tested this on other devices and this problem does not happen on them. Any clues on why this happen and/or any workaround for this for the Galaxy 5?

EDIT: This issue happens with the API Demos that comes with the Android SDK. To reproduce this error execute the demo and then follow: App-> Search-> Invoke Search -> click on App Data and start writing, on开发者_Python百科ly the lower half of each character will be rendered on screen.

Thanks!
