Just stumbled across this thread so not sure if it is still active?? My Asus Vivotab is doing the same thing... after going to sleep or putting the lid down, you have to drag up the logon screen and use the keyboard to enter the password, some of the swipes don't work and at times a bubble comes up on the screen or the cursor starts jerking around and there seems to be two cursors. It temporarily comes right when you restart it but overall the problem seems to be getting worse. I bought in the USA but I live in NZ. Is this a software or hardware problem? I have tried recalibrating and restoring to original settings. It was bought in December last year so not sure if it's still under any warranty. Any advice would be appreciated!!
