Steps to Reproduce:

Actual results:
gnome-shell crashes

Additional info:
The backtrace shows that this happens in input device handling. In this environment, mouse buttons (or touchscreen) sometimes stop working, and I've filed separete bug 1773815 for the issue.

Similar issues are reported in Fedora or Ubuntu, but the root cause is not identified yet.

Comment 3 Chris Kaltwasser 2020-05-11 14:10:57 UTC
I am having a very similar issue which I can reproduce every time. This is almost certainly a bug in Gnome.

The crash occurs after a large number, but fixed quantity of simple (button click) touch screen events.

I am using CentOS7 kernel 3.10.0-1127.el7.x86_64 and Gnome.

bug is written here: https://bugs.centos.org/view.php?id=17301

The system crashes after using a POS system we have running on a browser. 

We swapped out google-chrome, chromium and firefox browsers. 

We finally had to give up using gnome and switched to KDE.

Red Hat Enterprise Linux 7 shipped it's final minor release on September 29th, 2020. 7.9 was the last minor releases scheduled for RHEL 7.
From intial triage it does not appear the remaining Bugzillas meet the inclusion criteria for Maintenance Phase 2 and will now be closed. 

From the RHEL life cycle page:
"During Maintenance Support 2 Phase for Red Hat Enterprise Linux version 7,Red Hat defined Critical and Important impact Security Advisories (RHSAs) and selected (at Red Hat discretion) Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available."

If this BZ was closed in error and meets the above criteria please re-open it flag for 7.9.z, provide suitable business and technical justifications, and follow the process for Accelerated Fixes:

Feature Requests can re-opened and moved to RHEL 8 if the desired functionality is not already present in the product. 

Please reach out to the applicable Product Experience Engineer[0] if you have any questions or concerns.
