Hi,


Could be more clear about the behaviour of kwin without these options ?

I suppose that the behaviour would be the same as when all these options =

were checked ? (ie, maximize & fullscreen work on each screen =

independently, magnetic borders, ...)

What about persons who group monitors to do a huge monitor panel ? =

(video wall).
What about people who use very large monitor needing dual video inputs ?


My personal usage is (was) this one : I uncheck the option "Enable =

multiple monitor window fullscreen support" (all other options are =

checked). So that :
-> When working on my computer, the maximized windows spawn only one =

monitor at a time, I get magnetic borders, ...
-> When watching movie (fullscreen mode), the display spawns all my =

monitors thus doing a video wall.


Sorry, but what I see here is a powerful feature of KDE that is going to =

disappear ...


Regards,
Xavier

P.S. I am the "author" of the option "Enable multiple monitor window =

fullscreen support"
