Comment (by pulkomandy):

 This is reproducible in https://linuxfr.org/ as well:
 - Two vertical texts on the left (username and "R├ędaction") initially show
 at the correct place, but when scrolling the page down, they move to the
 down-left instead of moving up
 - I don't know if it is related, but also when scrolling, several icons on
 the page (for tags, pages with new comments, "proposer un contenu" button)
 disappear. I guess they are scrolled in the wrong direction and then
 clipped out

 I think fixing this would help with several glitches in WebKit rendering.
 It's probably a problem in handling transforms (applying them in the wrong
 order, using premultiply instead of multiply, or something like that).
