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 of problem:
Copying large text area (cca 200KB of plain text) through clipboard from Client to Guest doesn't work. Copying of the same amount of data from Guest to Client works fine. It's sometimes not able to display context menu after trying to paste the text to Guest application and sometimes even agents gets stuck (service running but agent doesn't work (losing mouse cursor for example).

Version-Release number of selected component (if applicable):
spice-server-0.7.3-2.el6.x86_64
spice-client-0.8.0-2.el6.x86_64
spice-vdagent-0.6.3-6.el6.x86_64


How reproducible:
Always (when using large enough text area).

Steps to Reproduce:
1. Open gedit in guest and client machine
2. Make large amount of text (200KB of plain text should be enough) in client gedit
3. Copy the text into clipboard in client
4. Paste the text into gedit in Guest
  
Actual results:
Nothing is copied and sometimes context menu cant be displayed or agent got stuck.

Expected results:
Text should be copied into gedit.

Additional info:.

This is very likely caused by the lack of proper flow control on the agent channel in the client to guest direction, which is bug 672191, marking this one as a duplicate.
