New commits: commit ec1a2322b862468621ce45500d74dac252bf1714 Author: Michael Stahl <[email protected]> Date: Fri Apr 22 18:09:39 2016 +0200 tdf#99460 sw: layout: don't split table before fly First the table is formatted properly and then the following paragraph is formatted, along with its anchored objects. The Fly frame is aligned to the bottom of the page by SwAnchoredObjectPosition::_AdjustVerRelPos() without checking for any overlap, and thus overlaps the table. Then SwFlyNotify and Notify_Background() invalidate the table's PrtArea, and the table responds by splitting numerous times, until finally there is a page where the table does not overlap with the fly any more. Instead of the table splitting, the paragraph with the Fly anchored to it should move to the next page; suppressing the table invalidation in Notify_Background() appears to achieve that.
