Description Dawn Morningstar 2022-03-07 17:02:36 PST 
imported/blink/svg/filters/filter-huge-clamping.svg 
Is a constant image failure on iPad queues. 

r289786 appears to be where failure started but further investigation is needed.

I was able to reproduce the failure at iOS 15 production ToT using the following test:

run-webkit-tests --ipad-simulator imported/blink/svg/filters/filter-huge-clamping.svg

Reduced testcase

We seem to go bad at a threshold of 4096 (4K).
Comment 6 Simon Fraser (smfr) 2022-03-14 15:49:01 PDT 
This does not reproduce in MobileMiniBrowser (with accelerated drawing on).
Comment 7 Simon Fraser (smfr) 2022-03-14 15:49:28 PDT 
Disabling accelerated drawing in WebKitTestRunner makes this bug go away.

I have marked this test as a consistent image failure while this issue is investigated.
