Motorola Xoom :: Performing Long Press / Drag Interruptions

My recently bought Xoom is randomly performing interruptions of the long press. While interruptions are going on, it doesn't prevent me from pressing, but it stops any long press just as if I had moved out the finger, with wicked effects:

- Any slow scroll gets interrupted;
- Selection with long press gets cut into a regular tap;
- Use of secondary characters on keyboard (via long press) becomes impossible;
- Swype turns into a regular keyboard, since the drag line gets constantly cut.

It's like the press had a variable timeout that comes really low, to a second or milliseconds. That happens frequently (but not always) right after boot/unlock. After that random period (from seconds to about a minute), everything works fine. It's not a lag or delay, it is an interruption, like a timeout.
