Perf flamegraph
Run with kf5 or kf6.
1. Open attachment 171031
2. Click the vertical scrollbar and drag down
Not seen with gtk3, gen or Windows.
It seems to have gotten worse in 7.5, but quite tricky to bibisect. On the
other hand, in older versions, scrolling back up freezes LibreOffice while in
current master it does not freeze.
Lots on time spent in SwLayoutFrame::PaintSwFrame
Michael: any idea about this?
