Description Andrei Stepanov 2015-10-26 10:17:15 UTC
Created attachment 1086440 [details]
Example for Alt-Tab

There is quite unpleasant behavior for fullscreen multi monitor setup.
Particularly, Alt-Tab event goes to client's windowmanager.
This can really confuse a user.

Bug takes place in setup with 2 (or more) real monitors.

Steps to reproduce:

1. Have a client with real two monitors.
2. Activate in virt-viewer additional monitors == real monitors.
3. Connect to VM with virt-viewer --full-screen

Each virtual display should be positioned on real monitor.

4. Move mouse pointer to one of displays. Open a window.
5. Move mouse pointer to other display. Do not click mouse.
6. Press: Alt-Tab.

Alt-Tab will be processed by client's WM.

There is work around: always click with mouse as you move to another display.
Nonetheless I find this behavior very annoying.

See attached screenshot.

Testing here (using rhel-7.2/f22 client connecting to rhel-7.2/f22 guest) and the only way to have the Alt+Tab handled by the client's Window Manager is when pressing Alt+Tab with the top menu (that contains the "Leave Fullscreen" button) focused.

Comment 3 Andrei Stepanov 2015-10-26 10:51:15 UTC
My setup has client 7.2
It doesn't depend on guest type.
It is reproducible without invocation the menu at the top.

Comment 4 Fabiano Fidêncio 2015-10-26 23:33:16 UTC
Hmm. I take the comment 2 back, I _can_ reproduce it here and it's quite interesting :-)
Every time you move the mouse from one display to another spice-gtk ungrabs the mouse and any keyboard event goes to the client's DE.

I can easily reproduce it with just one remote-viewer window, windowed mode, vertically maximized (Alt + {right,left}, when using GNOME). Just move the mouse to the "guest's area" without do any click and then press Alt + Tab, same behavior.

Andrei, does it happen with 6.7/rhevm clients as well? Can you check if it's a regression?

As I said before, I am able to reproduce it and I am using upstream spice-gtk/virt-viewer.

Comment 5 Fabiano Fidêncio 2015-10-27 16:48:53 UTC
Proposed a patch upstream for spice-gtk:

Currently the keyboard grab (redirection of key events) is related to a SpiceDisplay (virt-viewer's window), we can make it related to the application (session). IE if mouse is over any window of virt-viewer and any virt-viewer's window has the focus, then key events should be redirected.

Comment 7 Uri Lublin 2015-11-05 08:52:38 UTC
To reproduce at step 4 (from comment 0) I
4. Move mouse pointer to one of displays and left-click in it.

Comment 10 Andrei Stepanov 2016-03-30 16:49:26 UTC

virt-viewer-2.0-7.el7.x86_64
