Issue/Bug Description:
Seeing occasional freezes in the desktop, including mouse. System usually comes back after less than 30 seconds.

My syslog has many entries like this:

May 28 14:19:53 ryzen gnome-shell[4249]: pop-shell: [ERROR] mismatch on grab op entity
May 28 14:19:53 ryzen gnome-shell[4249]: error: Pop Shell Error: mismatch on grab op entity

I then see notifications from pop-shell in-app with the same mismatch on grab op entity error as small dialogs.

Steps to reproduce (if you know):
Not sure, sorry.

Expected behavior:
I don't expect my desktop to freeze!

Other Notes:

Not sure if this is related, but I was having poor performance and it was due to syslog being filled up. There are a lot of gnome-shell messages going to syslog.

How did you resolve it?

[dontlaugh]

Since it's my personal machine, I was okay with just deleting the giant log file.

rm /var/log/syslog

Closing because this isn't specifically caused by Pop Shell

Just curious, are we sure it isn't caused by Pop Shell? I have gotten this same error, and the notification clearly says "Pop Shell Error"

I'm having the same issue.
Only occur when I try to use the gestures on touchpad.

I'm also seeing this same issue. Tried clearing the syslog, but to no avail.

Just to add, I've been running PopOS for at least a year, this seemed to have started happening after a recent update.

I also have this issue, it's often happened when I run Android Studio and Chrome at once. The system will almost freezes and I should close Chrome or AS as fast as possible before it completely freezes, when I succeed in doing this lots of notification will appear like this:

I've uploaded my syslog here

So what is the solution ??
