After r268898 the ref-test compositing/clipping/border-radius-async-overflow-stacking.html fails on GTK. The failure is different depending on the display server so perhaps it has something to do with AC mode. * Failure for xvfb-x11/softgl -> https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/r268900%20(16593)/compositing/clipping/border-radius-async-overflow-stacking-diffs.html * Failure for wayland/intel-mesa -> https://build.webkit.org/results/GTK-Linux-64-bit-Release-Wayland-Tests/r268898%20(14631)/compositing/clipping/border-radius-async-overflow-non-stacking-diffs.html
Looks like I messed up the position of m_childClippingMaskLayer?
