Description

I have a dual-monitor setup managed by xrandr (both screens are part of the same X server) running xfwm4-4.12.5. When some applications that are running on the second monitor pop up a dialog, it appears on the primary monitor. Chromium (versions 70 and 71) exhibits this behavior, but neither Firefox, LibreOffice, nor xfce4-terminal do.

I bisected this down to the following commit:

commit e9d1de4c Author: Olivier Fourdan fourdan@xfce.org Date: Thu Mar 23 11:39:04 2017 +0100

placement: Use primary monitor as default

Reverting the above commit on top of the xfce-4.12 branch of xfwm4 and reinstalling resolves the problem for me.

Version: 4.12.0
