Yes:

$ xfwm4 --version
	This is xfwm4 version 4.16.1 (revision 5f61a84ad) for Xfce 4.16
	Released under the terms of the GNU General Public License.
	Compiled against GTK+-3.24.31, using GTK+-3.24.33.

	Build configuration and supported features:
	- Startup notification support:                 Yes
	- XSync support:                                Yes
	- Render support:                               Yes
	- Xrandr support:                               Yes
	- Xpresent support:                             No
	- X Input 2 support:                            No
	- Embedded compositor:                          Yes
	- Epoxy support:                                Yes
	- KDE systray proxy (deprecated):               No

Perhaps the missing XInput2 support is causing the problem?
