--- Comment #2 from Kimmo Kinnunen <kkinnunen at apple.com> ---
Thank you for the report.
This has likely the same root cause as bug 231471.

Most likely this has to do with ImageBitmaps being resident in the Web process and GPUP or Web process running out of memory. 
Symptoms are typically:
 - black texture 
 - GPUP crash via Jetsam.
 - GPUP crash via resource limit hit during memmove inside CG, probably when overcommitted allocation requests pages and fails

This can be reproed on macOS by loading the test case first thing after starting the browser.

This is alleviated by the bug 187964 which makes unrooted ImageBitmaps collected.
However, the browser should handle running out of memory more gracefully.
