Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

Reproducer
Description of problem:
Dialog/window with a preferred width greater than Short.MAX_VALUE, results in a dialog that functions similar to the expected dialog, except that instead of the expected components being displayed, the portion of the screen behind the display is copied into the dialog's panel. The functionality of the dialog is still working (example: copy/pasting cells, clicking buttons and getting dropdown menus, closing the dialog), but the display never gets painted correctly.
Some code within the Java libraries is forcing the width to be Short.MAX_VALUE. However, when this is too wide for the window manager (Gnome 3) to process correctly. Based on our testing, the most likely cause of this issue is that the pixel(s) that make up the border around the Java application are not being accounted for, and this is causing the window manager to use an invalid (probably 0 or negative) value when tracking the width of the window.
Version-Release number of selected component (if applicable):
mutter-3.28.3-5.el7
java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6
How reproducible:
Always
Steps to Reproduce:
1. Compile the attached reproducer as below:
$ javac PrefWidthExceedsShortMaxExample.java
2. Run PrefWidthExceedsShortMaxExample as below to reproduce the issue
$ java PrefWidthExceedsShortMaxExample
Actual results:
With default values of arguments, java window does not show up properly. With other manual arguments passed as below, results are as listed:
5000 a : Bad painting (width = 32767)
4096 a : bad painting (width = 32767)
4095 a : correct behavior (width = 32760)
10000 M : correct behavior (width = 32763)
10000 i : correct behavior (width = 20000)
10000 W : correct behavior (width = 32762)
10000 X : bad behavior (width = 32766)
10000 '&' : bad behavior (width = 32765)
Expected results:
Java window should always appear from end to end corners on the screen.
Additional info:
Tried the reproducer in KDE desktop environment and it works fine. So I suspect issue with the GNOME window manager.
Hello Olivier
I am sorry I missed your earlier note here. But since issue occurs only in gnome environment and not in KDE, I suspected the issue in mutter and filed this bug accordingly. I see you are referring to the upstream issue at https://gitlab.freedesktop.org/xorg/xserver/issues/661, which explicitly talks about crash in wayland. I don't think, we have having the same problem. Moreover yes, this reproducer can be used publicly as customer has not associated any specific license to it. Please let me know if anything is required from my end.
