The question is now irrelevant. Sergii’s changes have been merged today as 
nobody objected. Please feel free to test what did improve for your laptop 
setup.
As I wrote we expect that this get better for everybody. Maybe after a short 
hiccup phase in the beginning. I already had to commit a small fix for Sergii’s 
changes. But as I don’t have a multi monitor setup, I won’t see any of the 
benefits.

What should be tested now is for example centering a window on a screen. This 
should only take the current monitor into account not the complete virtual 
screen.
