Test case

Using backdrop filters causes screen corruption, outside of the safari window frame. This issue only happens on Catalina.

It was reproduced on a 14 core iMac Pro and on a 2016 MacBookPro 13", both running 10.15.4

This is another site using backdrop-filter, causing screen corruption in Catalina and Big Sur:

The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'.

This should now be fixed in shipping software.
