Severe lag on activation

[Novantric]

On Ubuntu 25.04 when I activate the extension, the whole screen stutters briefly for a short time, like 0.5 seconds, before progressing normally. Is this because of something like my mouse polling rate being 1000Hz, or my display being at 144Hz?
All the settings have been left on the default. I've just installed the extension for the first time.
Also weirdly when I try and screen record it seems to happen less often, so here's a video of my screen.
Thanks!

You can fix it by enabling 'Hide Original Cursor' in the extension's settings. It doesn't look great, though.

I wonder if we could set the index of the enlargened cursor above the original one. As far as I can see, it could completely cover the original cursor if done so, at least for adwaita cursor when scale is set to 96px

I found a solution to this problem, assuming you are using an Nvidia system.
Add these lines to your /etc/environment

GBM_BACKEND=nvidia-drm
__GLX_VENDOR_LIBRARY_NAME=nvidia

Afterwards, you will need to relogin/reboot.

The whole system will then start working much more smoothly and stably. The same goes for the Wiggle extension.

*note that some apps, like Spotify, will lose their Gnome borders and start looking like Windows XP. This can be fixed by forcing them to run in XWayland.

UPD: MUTTER_DEBUG_FORCE_KMS_MODE=simple makes system unstable when Adwaita windows being used.
Other variables still resolves the issue.

I've moved to Fedora 43 so can't test this until the extension supports GNOME 49, but thank you regardless.
