Created attachment 468256 [details] image diff Description: compositing/hidpi-compositing-layer-with-tile-layers-on-subpixel-position.html is constantly failing after on Sonoma MacOS on arm64. This issue can be reproduced by using the command: run-webkit-tests --release --iterations=1 compositing/hidpi-compositing-layer-with-tile-layers-on-subpixel-position.html The test is reproduced also on the last green commit so I couldn't bisect the regression.
