Disappearing mouse pointer

[Jerry James]

I use the default GNOME desktop, using Wayland with Intel graphics.  I
have a web browser, a terminal, and an editor running on desktop 1.
On desktop 2 (i.e., where Ctrl-Alt-Down takes you) I have virt-manager
running, with open windows for whichever VMs are currently in use.

Yesterday, I updated my Fedora 30 machine.  See the list of updated
packages below.  After rebooting into the new kernel, I interacted
with a CentOS 7 VM for maybe 10 minutes.  When I moved the mouse
pointer out of the VM window on desktop 2, the pointer vanished.  That
is, the mouse pointer is now invisible on desktop 2, except when it is
inside the VM window.  If I switch back to desktop 1, the mouse
pointer is visible, unless I move it onto the menu bar at the top of
the screen, where it also vanishes.

Logging out and then back in restored the mouse pointer, but after
working with the VM for just a few minutes, the mouse pointer
disappeared again, exactly as before.  Opening system settings brought
the mouse pointer back, for some reason.

I would like to file a bug on this, if it is not already a known bug.
Could this be due to the libinput update?  Before the following
updates were installed, I never saw this happen.  Now it seems to be
repeatable:

Weirdly I'm not seeing this on Fedora 30, I'm only seeing it on
Rawhide, and I haven't figured out a pattern because it doesn't always
happen.

Also I'm only using Rawhide VM's in virt-manager, so I'm not certain
the guest matters but that's speculative. Definitely it's related to
virt-manager and intel graphics because I'm not using anything other
than those two.

My Fedora 30 laptop has
00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake
GT2 [HD Graphics 520] [8086:1916] (rev 07) (prog-if 00 [VGA
controller])

My Fedora 31 laptop (with this transient issue) has
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd
Generation Core Processor Family Integrated Graphics Controller
[8086:0126] (rev 09) (prog-if 00 [VGA controller])

So it might be a controller specific bug, possibly kernel regression.
But I'm not sure what components are responsible for the drawing of
the pointer, and how it's negotiated when it transitions a
virt-manager guest window, and all the ways that could cause confusion
in a way to make the pointer vanish.

maybe https://gitlab.freedesktop.org/spice/spice-gtk/issues/83 or related to
it.

same here, but I am using only Intel graphics. Pointer disappears only out
of application windows, and sometimes it comes backagain
Filed a bug against gnome but not sure of the component. Reported link says

I'm seeing this with Intel graphics, but not involving virt-manager. My pointer
disappears when I open the GNOME 3 notifications dialog, and reappears when I move off it
or close it.

Recently filed bugs about similar issues:

https://bugzilla.redhat.com/show_bug.cgi?id=1738614
https://bugzilla.redhat.com/show_bug.cgi?id=1739169

Not sure if they are the *same* problem or different problems. They
look like the same issue (cursor only visible over application
windows) - but one reporter claims is started with a kernel upgrade,
and the other reporter reports an associated shell backtrace in their
log. And while a kernel upgrade could cause this (some problem with
overlays in the intel driver, perhaps), or the backtrace could
potentially cause this (shell is confused about what is an application
window and what is not), it's unexpected that a kernel upgrade would
cause the backtrace!

More information about a) whether that backtrace occurs for everybody
who is seeing the problem b) whether it was associated with a kernel
upgrade, and whether downgrading to an older kernel helps would
definitely be useful!

Do you think you could try downgrading your system to an older kernel? If
that fixes the issue, that woudl make it clear that it's not some other
package that was coincidentally upgraded at the same time as the kernel.

Thanks!

Same here.  It does seem to be the 5.2 kernel that triggered this
behavior.  I also managed to reproduce it once today without
virt-manager running, so maybe VMs have nothing to do with it.
Interacting with them seems to be the easiest way to trigger the
behavior, though.

I also experienced it today, no VM's running, no virt-manager running.
Just gnome-shell. I briefly had it consistently disappearing upon
pressing the super key (show activities), and then it would reappear
upon pressing super again (hide activities). And then I went to a
different computer with ssh into the one experiencing the problem, to
look at logs, but there were no messages at all in the journal for
this time frame (no kernel or shell message or anything at all). And
then just as inexplicably, the problem stopped, mouse pointer was
visible with activities showing and hidden.
