Created attachment 9114 mouse-cursor-upper-size.patch For HiDPI displays, KDE supports mouse cursor sizes 48 and 72. However, the size 72 cannot be selected because the upper bound in XFCE mouse settings is 48. This issue is fixed by a patch attached to this bug report. Please merge the patch into XFCE's git repository. Thanks.
