screencast showing the issue

SUMMARY
I was in the process of recalibrating my internal battery and had the charge graph open. All of a sudden I noticed the fan spinning up sharply. It turned out it was kinfocenter, whose GUI layout was fluctuating between two states when the windows is maximised. See the attached screencast.

kcms/energy: Fix page size flickering

Make the graph height relative to the page width, instead of the
column layout. This way it doesn't change when the scrollbar appears
or disappears, fixing the flickering loop
