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.

sandbox screenshot

Description of problem:
No matter what window size is specified when running sandbox (-w resolution), the sandbox window always opens too small. When the window is manually resized, the text is so small it's impossible to read (see attached screenshot 

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.15.0-15.el6.x86_64
policycoreutils-2.0.83-19.41.el6.x86_64
policycoreutils-python-2.0.83-19.41.el6.x86_64
policycoreutils-sandbox-2.0.83-19.41.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. make sure you have policycoreutils-sandbox and policycoreutils-python installed
2. run sandbox -X -w 800x600 firefox

Actual results:
A small sandbox window opens (not the size specified as parameter) and all the text inside the window is too small to read.

Expected results:
A sandbox window of specified dimensions is opened and text size is normal and readable.

Additional info:

This problem is also easily reproducible with Xephyr alone (assuming it's used by sandbox anyway) - specifying the -screen parameter is ignored.  This works fine with Xorg 1.13 shipped in RHEL-6.5.

Pretty sure this is fixed by
