** Description changed:
- 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.
+ Impact
+ -------
+ 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.
+
+ Test Case
+ ---------
+ 1. Install the update
+ 2. Log out
+ 3. Log back in
+ 4. If not already done, open the Settings app. Click one of the displays in
the list and set it to 200%. Leave your other display at 100%.
+ 5. Drag a window from one screen to the other.
+ The cursor and window should smoothly transition from one displays to the
other without the cursor jumping dramatically to a different location when it
crosses between the displays.
+
+ Other Info
+ ----------
+ Setting different scaling for different displays requires Wayland. This will
not work with the Ubuntu on Xorg session.
+
+ What Could Go Wrong
+ -------------------
+ This fix is included in the upstream mutter 44.1 release. See LP: #2020225
