@Caolan
There is overall improvement with you patch regarding to the more regular zoomlevels. But do noticing a wiggle in the example here with extreme zoomlevels. So <50% or >160%

Comment 4 Telesto 2021-12-23 12:39:28 UTC

No clue if it matters, but the same content doesn't wiggle in comment box
And well if you create a comment box at end of the line the wiggling stops too.

Which smells like bug 146078 & bug 140161

Comment 5 Caolán McNamara 2021-12-23 19:43:17 UTC

FWIW the new exploratory; tools, options, writer, view, glyph positioning: "layout" should give stable positions as seen in the comment box and other editeng cases. Hopefully in the new year we can tackle this

(In reply to Caolán McNamara from comment #5)
I don't see any UI element called "glyph positioning" in tools, options, writer, view.

its very new, yesterday or the day before: https://gerrit.libreoffice.org/c/core/+/127089

Comment 8 Caolán McNamara 2022-01-14 14:34:55 UTC

reproducible at 200% for me under windows, the W appears to go backwards on the insert. With new "Layout & Match Render" setting active it's stable.

Comment 9 Caolán McNamara 2022-01-18 20:41:52 UTC

I think with the new default we can call this one fixed in trunk
