Shared edges on multiple monitors
SUMMARY
When using multiple monitors with shared edges, one has to carefully aim the
mouse in order to hit certain corners. This goes against Fitts's law and can be
quite annoying.
For example, in the attached screenshot you can see the top and bottom edges
are shared. When clicking a close button on the left you have to aim carefully,
and the same applies when opening the launcher on the right.
Microsoft solved this problem using a "sticky corners" feature back in 2012.
You can see their description in the MSDN announcement here under "Improved
mouse targeting on the shared edge":

STEPS TO REPRODUCE
1. Move secondary monitor to share edge with primary monitor
2. Drag mouse all along the shared edge
OBSERVED RESULT
Mouse glides across
EXPECTED RESULT
Mouse stops at the corner
