RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Marian Krcmarik 2012-06-27 18:53:26 UTC 
Description of problem:
Changes (such as higlighting Menu item when hovering over them with mouse cursor, rendering moved app window when moving it with mouse, rendering moving scroll bar when drawing it with mouse) caused my mouse movement are not rendered after migration. 
-It happens when remote-viewer window is resized before migration only. 
-It happens in client as well as server mouse mode (in server mode cursor disappears).
-It happens on Linux as well as Windows guests.
-It happens on RHEL6.2 as well as RHEL6.3 hosts.
-It is observed until remote-viewer is closed/opened again.

Because It happens on Linux/Windows clients in client/server mouse mode I assume It may be a bug in spice-gtk.

Version-Release number of selected component (if applicable):
spice-gtk-0.11-11.el6.x86_64
virt-viewer-0.5.2-9.el6.x86_64
spice-server-0.10.1-10.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Connect to a Windows/Linux guest with spice agent installed and running.
2. Resize remote-viewer window to invoke guest resolution resize.
3. Migrate guest machine (keep mouse in guest, possibly move with it during migration).
4. Try to move an app window or invoke context menu and move over it with mouse.
  
Actual results:
Moved window is not rendered during moving it, Menu items are not highlighted as mouse is moving over them.

Expected results:
Rendered.

Created attachment 595628 [details]
patch for keeping the count of motion msgs in sync between the server and the client

The counting of motion messages was not synchronized between the client and the server after migration. This can lead to not delivering mouse motion updates to the guest; while mouse press events are still sent. This can explain the behavior Marian described.
The attached patch synchronized the mouse count.

Hi Marian,
Can you try this scratch build https://brewweb.devel.redhat.com/taskinfo?taskID=4565938 ?
Thanks.
