Do you use Wayland or Xorg? Try to switch to Xorg.
After installation of an extension often a reboot/reload of gnome is neccessary. So reboot or logout and then login again.
If that doesn't help try to disable the extension, logout and then enable it again.
Which nvidia card do you have and what graphics driver do you use?
I shortened this thread title given that the first post describes the issue.
RTX 4080 graphics card

This thread and the other thread
"Blur My Shell graphical glitching"
can be put together.
I agree - there are two separate issues:
- Nvidia driver
- Blur my shell
It has been established that @cyberman is already on the latest driver.
