Hi, I have opened an issue about PositionPlacement Center style: after the recent changes, in multi monitor mode, this centers window split between left and right monitor, while with latest fvwm3 release, this was not the case. Using dv/pager-noaspect where the current issues have been resolved couple days ago. It is repeatable on the current master.
Here it is. together with the screenshot of the area between monitors. https://github.com/fvwmorg/fvwm3/issues/648 -- Miroslav
