What might cause windows to be redrawn exceptionally slowly on Ubuntu 22.04 running nvidia graphics?

I've seen the following problem a couple of times now running 22.04 but have never seen it before on my Ubuntu installation (running same hardware).

You can see a video of this in action at youtube.

You will see that windows move extremely slow as I drag them across the screen.

Here are details of my system:

It's not the main processor, it is that suddenly graphics processing seems to be effected.

What might cause this?

I discovered that this stopped occurring when I closed an app which is using a component WebView2.

I then started the app again and the odd slow behavior started occurring again.

It seems that the WebView2 component causes this to happen.

I'm also running FireFox 107.0 64-bit but even if I close that (and all other apps) and only run the app which contains the WebView2 component do I see the problem.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
