Screen capture demoing the issue (GIF, ~4 MiB)
In some websites, after hovering an element which changes the background, the original
background is not correctly restored when the element is not hovered anymore. Check the
attached GIF for a demo of how this looks when the issue is triggered by PhpReport
(<a href="https://github.com/Igalia/phpreport">https://github.com/Igalia/phpreport</a>).
This happens both an AC and non-AC modes, but only in HiDPI: manually setting the
window scale factor to 1x in GNOME Tweak Tool makes the glitches go away.</pre>
