@foone maybe it is emulating (the kerning of) MSWord.

@foone Usually when this happens, it goes away if you force a redraw of the text (by, say, zooming in and back out).My theory is that LibreOffice has some issues where the pixel offset of a particular character can get off by one, and then it just propagates through the entire rest of the document.

@foone Can I ask what font, OS, and LibreOffice version this is? I did a lot of research on this in the past and contributed to bug reports at the Document Foundation about the issue.This looks like a failure to use subpixel positioning on the glyphs, so the position of the 'a' glyph is rounded to the nearest glyph and looks very weird. LibreOffice switched to using subpixel positioning for all rendering with version 7.4, but I could imagine this happening with weird font / hinting settings.

@fontenot Sure!It's Liberation Serif, Windows 10, and LibreOffice 6.3.3.2. (I haven't updated it in a while so that's probably way out of date)

@foone Oh cool, thanks! Yes I think if you try out 7.4 you'll find the problem goes away. It looks like just the rounded glyph position issue, I have a whole blog post about it: https://adamfontenot.com/post/libreoffice_7_4_has_a_new_approach_to_text_rendering

@foone maybe that's also a hinting issue?

@foone So now you will revert to see if you had screwed a setting or if they actually addressed the problem? :)

@foone and you removed subpixel antialiasing.

@foone Maybe you also changed your zoom level or font size? The revised text is quite a bit larger (when you reverse the upscaling on the original image).I'm curious whether, at the same size, the shape of the 'c' glyph is as cursed as it is in the before image. I can't think of any LibreOffice bug that might cause that, although they've done some strange things on Windows in the past IIRC.

@fontenot I didn't fiddle with the zoom in LibreOffice, I just forgot to rescale the screenshot when I posted it to mastodon

@foone Interesting! After correcting for the upscaling, many of the glyphs in the fixed version are wider and thicker than before. (And a few are narrower.) I'm not sure what caused this, but clearly the subpixel positioning is making a huge difference here.
