Causes freeze and stutter

[TheWeirdDev]

Enabling this extension causes my screen to freeze (stutter) every one or two seconds. I suspect this is because it runs synchronously on the main gui thread and the extension stops for a fraction of a second to read and reload the status.
I'm not exactly sure but making the refresh functionality asynchronous might fix this issue.

This is one of my favorite extensions but this problem makes it almost unusable for me.
I'm running ArchLinux with gnome-shell 3.36.4 on X.

Thanks for your work.

Hi.

I'm sorry to hear that. How recent is this problem?
Where did you get the extension from? This repo? The gnome extension website? The AUR maybe?

It is weird because it sounds like an old memory management bug that was patched months ago…

After enabling the extension and launching a terminal, what does these two lines show?
journalctl --since "1 day ago" | grep nordvpn

journalctl --since "1 day ago" | grep nvpn

I've had this problem for a long time (6 months or so).
I installed it from the gnome extension website and now i reinstalled it from this repo but it has the same problem. Someone on the gnome extension website pointed out that they have encountered this bug too.

Enabling the extension and running those commands didn't output anything.

My bad: can you try this with admin privileges?

[TheWeirdDev]

Running commands with sudo outputs the same empty result.

i'm also getting stutters. im on a fresh install of fedora 33. i installed this gnome extension instead and don't have any problems: https://extensions.gnome.org/extension/2569/gnordvpn-local/

[AlexPoilrouge]

Well, I'm sorry to hear that.

But as I said, I have no clue where this bug is coming from, and, more importantly, I can't reproduce it. And I can't just make guesses and cluelessly change the code since I won't know if the fix actually work or not.

So, until I find more clues, you should stick to gNordVPN-Local, sorry.

Exactly the same on Ubuntu 20.04 up-to-date

I have the same problem on Manjaro Linux (Kernel 5.4 LTS, NVIDIA 455.xx).

Downloaded from AUR.

journalctl --since "1 day ago" | grep nvpn

Tested with https://www.testmyscreen.com/ best seen with the sport pan mode. Heavy freezing with it enabled.

Found it with this post:
https://askubuntu.com/questions/1105528/ubuntu-18-04-video-stutters-every-second-regularly-with-nvidia-gpu
"It turned out that I had one of my gnome shell extensions (SystemMonitor) update values every second, and as soon as I turned this off it no longer had a stuttering issue. Why exactly that was the problem I am unsure, but turning it off fixed it."

Could this be the problem?

[jvanheugten]

Had this exact same problem just now.
It seemed that nordvpn wasn't logged in, and somehow the extension tried to force login, causing too many requests. It then was hanging my whole system every few seconds.

nordvpn login
Too Many Requests

Currently have the extension disabled.

I have a similar problem, screen stuttering and when I firstly click on the NVPN icon to open the menu, everything freezes for a few seconds, then the menu opens. Every interaction.
I changed the refresh time to 5s and the mechanism to identify nordvpn from "hash" to "which", and apparently things were better (but I'm not sure if this is the solution or just a coincidence).
