Will have a play and see if I can replicate.
That´s a Kindle PaperWhite 3G + WiFi (Europe)
nearest thing I have is a touch...
see what happens
OKAY: So if you mean the top part of the screen...
This is noted under KUAL known issues
IIRC. Let me go find it.
EDIT: No it was noted HERE
I have copied the info across and made it clearer.
It´s not really an issue in KUAL per sé, more an issue with X not seeing the FrameBuffers´ changes
The solution is posted as pictures.
If this is the issue you meant let me know. Then I can stop looking for problems
