Another instance of the dashed line problems - comment on recent FOSDEM Heise -
in German about this despairing about performance of LibreOffice:

wget
<a href="https://github.com/oliworx/LibreOffice-vs-OpenOffice/raw/master/Kassenbuch_2018.ods">https://github.com/oliworx/LibreOffice-vs-OpenOffice/raw/master/Kassenbuch_2018.ods</a>

This spreadsheet renders horribly slowly despite being rather trivial. The
problem it turns out is the fine dotted line borders used in a few places.

I attach a perf top flamegraph picture - though the load this puts on the X
server is also quite significant.</pre>
