I have looked into this bug before. From what I recall there was a fundamental conflict between:
(a) Keeping the absolute cursor position on both monitors' boundaries when crossing; and (b) Keeping the relative cursor position on the titlebar. So mutter chose (a) over (b). More recently however, upstream claim to have solved (changed) it in mutter 44.1: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2942 ** Package changed: gnome-shell (Ubuntu) => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: New => Fix Committed ** Bug watch added: gitlab.gnome.org/GNOME/mutter/-/issues #2029 https://gitlab.gnome.org/GNOME/mutter/-/issues/2029 ** Also affects: mutter via https://gitlab.gnome.org/GNOME/mutter/-/issues/2029 Importance: Unknown Status: Unknown ** Changed in: mutter (Ubuntu) Importance: Undecided => Low ** Tags added: fixed-in-mutter-44.1 fixed-upstream -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2015861 Title: cursor does not track window when dragging between monitors with different scaling factors Status in Mutter: Unknown Status in mutter package in Ubuntu: Fix Committed Bug description: I have two screens. My laptop is using 200% scaling and the other external screen is using 100% scaling. When I drag windows between the monitors the cursor moves to unexpected locations when it moves onto another screen with a different scaling factor. I would expect the cursor to stay in the relative location when I started dragging the window. Hopefully this is clear the the attached screencast.
