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:

Version-Release number of selected component (if applicable):
RHEL 6.4 Beta. 

How reproducible:
100%

Steps to Reproduce:
1. install 
2. boot
  

Additional info:

I'm happy to try out any test packages and/or provide additional info. Thanks.

xorg log

Comment 3 Adam Jackson 2012-12-11 15:13:42 UTC
Odd, the X log certainly thinks GL is working.  Can you attach the output from glxinfo?

Comment 4 Ben Breard 2012-12-11 17:06:52 UTC

glxinfo

Here you go.

Comment 5 Ben Breard 2012-12-14 05:48:56 UTC
I should add that Gnome seems to work fine with compositing. This only effects the version of KDE that ships w/ RHEL 6. All previous minor releases of RHEL 6 worked perfectly. Than seems to think this is more likely an issue w/ mesa that Xorg. Any idea how to track this down?

Comment 6 Ben Breard 2012-12-15 01:46:42 UTC
I can confirm that downgrading mesa* to 7.11-5 fixes this issue. Apparently the rebase of mesa is what's causing problems with KDE. I've reassigned this BZ to mesa. Please let me know if there's any other debug info I can provide. 

This is 100% reproducible.

Comment 8 Dave Airlie 2012-12-17 02:44:35 UTC
okay I've ruled out MSAA as the culprit, now sure where to go next, kwin isn't the most verbose with its info.

Comment 9 Dave Airlie 2012-12-17 04:13:11 UTC
okay more info, this is due to kwin forcing an indirect context and that breaking.

running KWIN_DIRECT_GL=1 makes it work, so we need to track down what broke indirect context for kwin.

Comment 10 Dave Airlie 2012-12-17 05:54:08 UTC
okay two issues

a) indirect rendering was broken, patch posted upstream, and here

b) msaa confuses kwin.

will work out the fix for (b)

Comment 11 Dave Airlie 2012-12-17 06:08:31 UTC
This will require an X server bug as well.
