dasyatid1 | Offline word processor recommendations?

I find myself wanting an offline traditional word processor. For some documents where other people are involved I've been using Google Docs's word processor, and I actually quite like it from an interface standpoint—but I'd really rather not be locked into Google for other local documents. The most important thing this hinges on seems to be document style-set support, which is also congruent with how I write HTML sometimes. In general I care about very solid support for WYSIWYG rich text here, including HTML-like structure, rich inline styles, and proportional typesetting, which mostly excludes my otherwise-lovely Emacs from being suitable unless there's a really good mode I don't know about.

Things I've tried, all on my Arch Linux desktop:

LibreOffice Writer has horrifically distracting UI flickering when I move my cursor over the formatting toolbar. Toggling the hardware acceleration option in Tools → Options → LibreOffice → View does nothing. I think the schema on the style support looks workable, but when I open the Styles and Formatting sidebar, that flickers too, and it's actually bad enough that I can't find out. It looks like bug #112889 aka “Flickering-UI” might be related, but the dependencies of it (which seem to be sub-bugs / independent reports) often talk about this only happening when OpenGL rendering is off, and if that's the same as the hardware acceleration toggle then that doesn't fix it for me.

In Calligra Words, when I open the style manager, the zillion bibliography and contents styles cluttering things are a relatively minor barrier, but all the styles mysteriously displaying with a parent style of “Alphabetical List” and a next-paragraph style of whatever the dialogue selected first is not confidence-inspiring. Spacing is in centimeters, which in most contexts I like, but I actually do typography in points and inches and I care about matching base line spacing—oh, wait, I just saw in the “Customize” dialog that it's configurable, but it doesn't take its default from my LC_MEASUREMENT nor LC_PAPER settings? Ergh. Also the font selection is pretty hard to navigate, which doesn't seem uncommon for desktop FDO/Linux applications, but still ergh.

Things I haven't fully tried yet:

AbiWord seems like it might actually be workable, though the cluttered nested dialogs for style editing are awkward. This is kind of a surprise to me, because I'd expected AbiWord to get the least development support over the last decade or so. Or maybe that's why it's like that?

Some sites suggest WPS Writer which I hadn't previously heard of… proprietary from a vendor of unclear trust.

I was hoping an HTML editor like Bluefish might work, but at a glance it doesn't seem to be WYSIWYG.

Any thoughts on how to best support this use case? I'd almost be tempted to go Microsoft, but last I checked they might be expensive and have gone cloudpusher too and in any case won't work well on FDO/Linux. Proprietary software is dispreferred but potentially okay.
