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.

SPICE protocol supports copy-paste for different types of data between client and guest. This mechanism is broken when users tries to copy an image from Windows10 Guest and Paste it to Client.

Guest: Windows 10
spice-qxl-wddm-dod-0.18-1
vdagent-win-4.1-3

How reproducible: always

Steps to Reproduce:
1. Log in to Admin or User portal.
2. Have a running Windows 10 VM.
3. Connect to remote desktop of the VM.
4. In the Windows10 open a paint program.
5. Copy an image from paint.
6. Try to paste image at client.

Actual results: cannot-copy paste image data from guest to client.

Additional info: This bug doesn't depend on client.

Could you please attach the logs from vdagent-win and the client?

Also, could you please double check if this also happens on windows 7?

The image (bmp/png) copy/paste failure is a known issue with the
mingw build and has already been fixed upstream.
To be fixed on the next build.

Copy-paste image bug from Guest->Client has place only for Windows10 guest. Windows7 guest doesn't have such bug.
