    <thetext>mix-blend-mode failing when window width width crosses 2048px.

Youtube video 

https://youtu.be/xZoVOjGKnD8

In the video I&apos;ve added some js to the console to output with the window width.

Source website - https://www.eternalproject.eu

Also found this example online (not authored by me) - https://hokuto-kato.github.io/sandbox/mix-blend-mode/

You can see a reproduction here - https://codepen.io/crisward/pen/rNXyWwN - resize &gt; 2048 wide a the dots become opaque.

Also reported in safari 17 within a redit post, but unclear if its the same bug as they only mention window resizing and not the specific width above.</thetext>
