Subject: Remove useless SinglePar update when scrolling in text
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=2bdd691130e5507fc5cc2ca81e71eef189e90fc5;p=lyx.git

Remove useless SinglePar update when scrolling in text

Using SinglePar does not majke sense here since the paragraph is not
modified and it might even not have a position yet.

This fixes a crash in BufferView::singleParUpdate, which is not
prepared (yet) to such situations.
