I have a meeting about this soon though. If and when we have an SPI that works from the GPUProcess (and with acceptable security ramifications), I will update our code accordingly. For now, doing it from the WebProcess is that best we can do and the approach we have taken in Bug 220663 as well. 1720987 4 417977 ggaren 2021-01-20 13:55:02 -0800 Comment on attachment 417977 Patch r=me 1720991 5 ews-feeder 2021-01-20 14:07:54 -0800 Committed r271673: <https://trac.webkit.org/changeset/271673> All reviewed patches have been landed.
