>I was unable to reproduce this problem.
Sorry, but this is definitely something within your page. I even ran "Incognito" mode which switches off all the extensions and still able to reproduce this behavior. I provided my specs below. As for the DOM tree, nope, nothing unusual here, at least near the buttons.
Some hints for you:
- window is fully maximized (1920 width)
- page is in its tops, i.e. window.pageYOffset === 0
- Night Mode is on
- left bottom corner of the rectangle always visually matches the point where the check mark disappears (probably some leftover of svg transformation?)
Reproducible with 100% chance only on that specific red button under those conditions, but every button has this effect, more or less, as you can see on the video.
