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.

Doc Text:
.Interacting with a `wacom` pen works on the gnome shell Previously, interacting with the shell frequently triggered the backtrace and the gnome shell was unresponsive. As a consequence, the stylus tip was not working, the stylus cursor was hidden whenever scrolled over a window, and the mouse button stopped working. With this update, `gnome-shell-3.32.2-9.el8` package is added in RHEL 8.1. As a result, interacting with the `wacom` does not make the gnome shell unresponsive.

Description Peter Hutterer 2019-06-04 05:43:16 UTC 
Description of problem:
Interacting with the shell frequently triggers the backtrace below, at which point gnome-shell becomes largely unresponsive.

Version-Release number of selected component (if applicable):
gnome-shell-3.28.3-10.el8.x86_64

How reproducible:
I'm not 100% sure but it's related to dragging something with the tablet stylus.

Most reliable way is to use the stylus to drag items in the dock. Some of this will trigger bug 1716767 but eventually that bug doesn't happen and instead the backtrace shows up in the log.

Actual results:
- Activities doesn't work anymore and neither does the hot corner (super key works though)
- the stylus tip may or may not work, it's a bit random
- the stylus cursor is hidden whenever it moves over a window

The above isn't reliable either, after a while the mouse buttons may stop working too, etc.

Additional info:

When triggered, there are tens or hundreds of these in the journal:
