Description Said Abou-Hallawa 2022-10-09 17:41:14 PDT

Drawing the form controls have to happen in WebProcess because the NSControls can't be shared. We have to draw them to an ImageBuffer in WebProcess and send the ImageBuffer to GPU Process. Because IOKit will eventually be blocked in WebProcess, the temporary ImageBuffer has to be unaccelerated.

We decided to take a different approach for this problem by drawing the control parts in GPUP using AppKit and CoreUI. See bug 249168.
