This happens with images that have a channel depth of 1-bit in a channel (e.g. solid color images such as https://bug-219977-attachments.webkit.org/attachment.cgi?id=421723). The underlying WebP issue was logged in https://bugs.webkit.org/show_bug.cgi?id=219977 but previous versions of Safari handled the error gracefully (logging "Cannot decode the data in the argument to createImageBitmap") and error handling in sites/apps could handle the error successfully. Since Safari 15.2, the error isn't handled and causes the tab to crash. https://jsbin.com/cetawaqudo/edit?js,output is a basic reproduction using the black square image from above. 1841562 1 webkit-bug-importer 2022-02-14 19:58:42 -0800 <rdar://problem/88943597> 1842036 2 ap 2022-02-15 16:59:29 -0800 This looks like a duplicate of bug 231794. Can you reproduce this with Safari technology Preview? 1842489 3 ryan.hamley 2022-02-16 13:26:34 -0800 I couldn't replicate this in Tech Preview 140 so I think this is likely a duplicate and has been fixed. Thanks! 1843661 4 ap 2022-02-18 14:51:38 -0800 Thank you for confirming this! *** This bug has been marked as a duplicate of bug 231794 *** 451964 2022-02-14 17:07:37 -0800 2022-02-14 17:07:37 -0800 Solid black WebP image color_000000.webp image/webp 54 ryan.hamley UklGRi4AAABXRUJQVlA4TCIAAAAvV8KVAAcQEf0PACjS//8U0f/U//73v//973//+9///oce
