This seems to be cause by software rendering. @MortimerGoro Maybe we can enable hardware rendering for history and bookmarks?

Disabling async layers also causes the issue to go away. So this seems to be some sort of interaction between software rendering of large UI textures (history, bookmarks) and Oculus async layers.

We can try but I'm concerned that having both render modes in different views in the same window can cause more bugs.

Another thing we can try is ignore all renders after onStop/onDestroy is called (trying to find a workaround for the original crash without using soft rendering)

I'm wondering if there is something going wrong when we replace the browser window with the history or bookmark widget. I don't see this issue with the tabs window.

I have verified that this issue is no longer reproducible with the latest Firefox Reality version 8-40101959 (3c2a71e) installed on the Oculus Go and Oculus Quest headsets.
Now, the movement is no longer choppy and there are no glitches in the Bookmark/History Views regardless of the window size.
