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 Alain D D Williams 2018-05-12 16:13:15 UTC 
Description of problem:

A gnome terminal session will hang after a switch to something else (eg evince - and do a page-up) and then back to gnome terminal. Typing characters does nothing, but scroll the mouse (or double-click a word) and it reawakens and the typed characters are sent to the application.

It does seem to depend on the application being run under gnome terminal; it happens with mutt, but not vim.

Attaching the application (ie mutt) with strace some how ''fixed'' the issue; then I ran strace under xterm (ie not gnome terminal) and the 'protective' effect of strace did not happen.

I also saw this affect bash (when I suspended mutt with ^z).

If I ran mutt under xterm I do not see this behaviour.

Gnome terminal 2.31.3

x86_64 fully up to date - CentOS

This first appeared after I ran an update that installed the components below and I then rebooted due to the new kernel. Do however that a new version of VTE was installed, I suspect that this is the change that made this problem.

Comment 2 Debarshi Ray 2018-05-16 16:05:55 UTC 
Sounds similar to bug 1546615
Comment 4 Alain D D Williams 2019-07-03 12:59:51 UTC 
Why is this marked WONTFIX ? Is it because RHEL 6 has not got long to live ?

I cannot see bug 1546615.
