Title:
Cursor Tracking with Gnome Shell Magnifier on Wayland
Status in GNOME Shell:
Fix Released
Status in gnome-shell package in Ubuntu:
Fix Released
Bug description:
Affected version
GNOME 3.36 - 3.40.
Ubuntu 20.04, 20.10, 21.04 and Fedora 34 Beta.
Wayland only.
Bug summary
When running GNOME shell with Wayland, the cursor and focus tracking
functionality of the magnifier (a11y feature) do not correctly compute the
cursor/focus location. The position is calculated from the top left of the
window but the windows position is not included. This causes the magnifier to
track the wrong location when the window is not maximiser or is on a second
monitor.
I suspect this is related to the way in which wayland is designed. But
my experience in this area is minimal. When using X11 this feature
works correctly.
The wiki page states that under wayland the cursor and focus tracking
work but this information is either out dated or was not tested
correctly.
Steps to reproduce
From the Gnome desktop, open a terminal by pressing ctrl + alt + t or by
opening the activities overlay and searching for "terminal".
Press super + left arrow key to maximize the terminal window on the left side
of the screen.
Activity the magnifier by pressing super + alt + 8.
Type text into the terminal window. The magnified view will move with the
text cursor.
Press super + right arrow key to maximize the terminal windows on the right
side of the screen.
Type text into the terminal. The magnified view will move but it will not
show the text cursor. It will move when text is entered but will focus on the
left side of the screen.
What happened
The magnified view does not follow the text/focus cursor correctly.
What did you expect to happen
The magnified view should follow the cursor and show the cursor as it does
when the widnows is maximized. The correct behaviour can also be seen in Gnome
shell running with X11.
