Possible Nvidia Graphics Driver Issues

[Provisional9448]

I reported issues on the GNOME Extensions page and was told to follow-up on GitHub. The extension has graphics instability issues on my hardware and I'm not sure why. I have disabled all other extensions to try to isolate the issue, but I'm still experiencing the same problem.

The hardware I'm running Fedora 36 on is a Thinkpad T480 with a disabled Nvidia MX150 GPU. I disabled the Nvidia GPU by blacklisting Nouveau in /etc/default/grub. I did discover that I have Nvidia firmware nvidia-gpu-firmware-20220913-140.fc36.noarch.rpm installed via the Fedora updates repo. I'm not sure if that particular firmware is affecting the graphics at all, but I'm doubtful because I don't have Nvidia graphics drivers installed.

One note about the Thinkpad T480: as I understand it, only the integrated GPU is wired to display outputs, meaning the iGPU would still be handling outputs even if Nvidia graphics drivers were installed.
