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:
After updating from Xorg-1.15 to Xorg-1.17, screen redrawing is not done properly, when using "overlays" with the NVIDIA diver.
For example, when a menu pops-up, it stays up even after closing it. It stays "on top" of everything else, effectively blocking the view of anything which is at that part of the screen.
Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.17.4-9.5.el6_8.x86_64
How reproducible:
Updating the Xorg server on this system and using the GUI normally.
Steps to Reproduce:
see above
Actual results:
Areas behind pop up menus and windows are not redrawn after that menu/window is closed. That area of the screen remains unusable as things that were there are now obscured.
Expected results:
Screen areas behind open menus and windows should be redrawn and that space usable again.
Additional info:
--Downgrading Xorg back to 1.15 resolves the issue.
--NVIDIA video driver is being used. Customer has tested with different versions of the NVIDIA driver. The version seems irrelevant, as the issue still occurs.
