I have the same problem sometimes, when it happen I press the touch media key in the middle right side of the phone, and enter to the pictures aplication and exit touching the screen, this appear to recalibrate the touch pad most of the times.

SOURCE: LG Xenon keypad slid open will not turn horizontal on the screen

I read that you can rub a magnet on the backside of the slider and it makes the screen turn portrait and horizontal - you can see that when you rub the magnet on the backside. I just rubbed the magnet with the slider open on the horizontal side (only the right side) - if you rub the left side it makes it portrait. I did that a few times and my phone turns horizontal now when I open the keypad slider. It appears to have worked doing this at this point.

The problem has nothing to do with the firmware, it is an issue with a cable in the phone. This cable connects the motherboard to the keyboard. When the phone is slide back and forth is causes the image to blur, get lines down the middle, or white out completely. Depending on your carrier, they should be able to:
Unscrew the phone, opening the phone up revealing the motherboard
Unscrew the motherboard
Pry the motherboard from the phone (on the other side of the motherboard there is a cable attached to it, you need to get that cable replaced)
and it's FIXED!

DEAR FRIEND, YOU WILL HAVE TO CHANGE THE TOUCH PAD OF YOUR PHONE.
