0. Demo barely rotates/animates
1. Some browser UI actions become extremely laggy. Example: Opening new tabs, profiling the demo etc.  Recording profile and capturing it usually leads to complete hang of the UI.
2. The Windows UI becomes somewhat laggy
3. 95% "GPU copy" as shown by Windows Task Manager. From doing the bisection, high "GPU copy" is strongly correlated to the above 3 symptoms

Good (1Oct2023) : https://share.firefox.dev/3Sx2xn3  (98% GPU 3d use, 0% gpu copy)
Bad(17Jan2024) : https://share.firefox.dev/490c6Qr (70% GPU 3d use, 85% gpu copy)

4. The gpu use continues for 10s of seconds after you close the tab. Expectation would be that as soon as the offending tab is closed the processing should stop (and the UI responsiveness improves)
