In case it might help, this seems a recurrent stack trace during the slowness
writev,??,??,xcb_writev,_XSend,XRenderAddGlyphs,QFontEngineX11FT::uploadGlyphToServer(QFontEngineFT::QGlyphSet*,,
QFontEngineFT::loadGlyph(QFontEngineFT::QGlyphSet*,,QFontEngineFT::recalcAdvances(QGlyphLayout*,,??,??,??,??,
QTextEngine::shapeTextWithHarfbuzz(int),QTextEngine::shapeText(int),QTextEngine::shape(int)
likely with this sequel [1], so the innermost LyX code seems:
lyx::frontend::GuiFontMetrics::breakAt,lyx::Row::Element::breakAt,
lyx::Row::shortenIfNeeded,lyx::TextMetrics::breakRow,lyx::TextMetrics::redoParagraph,
Now, I'm just moving the cursor and sometimes selecting with Shift down, so do
we actually need to redoParagraph() ?
Thanks,
T.

I'm now trying oprofile/operf, just to compare output.
that's quite similar
