Title:
Non-integer X11 scaling causes mouse from login screen to stick around
Status in gnome-shell package in Ubuntu:
Confirmed
Bug description:
If you enable fraction scaling and then login using an X11 session,
the mouse cursor that existed on the login screen (gdm3) will persist
after logging in. This mouse cursor continues to exist at the same
pixel coordinates as when the login was completed. A new mouse cursor
is then created for that login, which is controlled by the mouse. The
original cursor that persisted from the login screen now becomes
static and can no longer be moved. However, like any mouse cursor, it
hovers over all windows and the desktop, which is quite distracting
when the cursor is in the middle of the screen.
This extra mouse cursor can be eliminated by switching to a non-
fractional scaling mode. Once it is eliminated, you can then switch
back to fractional scaling and the extra cursor will not return.
Seeing this, I have worked around this issue by adding a startup
script to my session that toggles the scaling mode between integer
scaling and my desired fractional scaling mode. Obviously this adds a
bit of extra flicker to the login process, though, so it's not ideal.
Note that a similar bug has been reported previously (#1827428), but
that bug was closed in the Ubuntu 19.04 EOL.
