Description

I have a tripple monitor setup as follows, it consists of one screen in Portrait mode, then one in Landscape and then another monitor in Portrait mode:

xrandr --listmonitors

Monitors: 3 0: +*HDMI-A-0 1920/518x1200/324+1080+480 HDMI-A-0 1: +HDMI-A-1 1080/527x1920/297+0+271 HDMI-A-1 2: +DVI-D-0 1050/408x1680/306+3000+0 DVI-D-0

When I drag a window from a large monitor to a smaller monitor and drag that window e.g. to the top border of monitor 0 to TILE_UP, sometimes the window is maximised on monitor 1 instead of monitor 0. But when I tile to a corner, the window is always displayed on monitor 0.

I believe this is because in moveresize.c:clientMoveTile all TILE_'s are done by calling clientTile directly while passing xevent->x,y but TILE_UP is triggered by calling clientToggleMaximized without passing xevent->x,y information. And as clientToggleMaximized always finds the current monitor by looking at the center point of the window, it could be that with dragging windows from a big to a smaller monitor that center point is not on the same monitor as the mouse is.

Before I write a patch, would you consider this a bug or a feature?

As a patch i think you would need to pass (optionally?) the 'current' x,y variables to clientToggleMaximized so it will only use the center point of the window if there is no x,y available.
