If I turn off the experimental feature- GPU Process: Canvas Rendering, everything works as expected. And it worked as expected in previous Safari versions. 1848323 1 webkit-bug-importer 2022-03-04 09:16:40 -0800 <rdar://problem/89817412> 1850949 2 peter.parks.eron 2022-03-14 11:13:47 -0700 I guess that it started with the first version that included GPU Process: Canvas Rendering as On by default. 1856564 3 jer.noble 2022-03-30 14:03:59 -0700 This appears to work correctly now: <https://jernoble.github.io/samples/bin/video-to-canvas/hls.html> Peter, would you mind testing with a recent STP build?
