Now I can not reproduce this potential bug anymore. I did all the variations of what you said hawhill (Kindle: landscape/portrait & KPV: landscape/portrait) and in all modes there seems to be no issues. Mind saying you that I put the device into sleep manually by sliding power button.
I have no idea why those glitches used to happen! Maybe other people have noticed it under some circumstances!? I can't reproduce it.
