New commits: commit 4102a92b319afc5140c9b2adc4483a6643334b3a Author: Michael Stahl <michael.st...@cib.de> AuthorDate: Fri Nov 13 20:51:42 2020 +0100 Commit: Michael Stahl <michael.st...@cib.de> CommitDate: Tue Nov 17 10:33:26 2020 +0100 tdf#138039 tdf#134298 sw: layout: fix overlap of fly and table The layout is horribly borked, the fly anchored in the body-level paragraph messed with the preceding table: page id="1" top="284" width="11905" height="16837" bottom="17120" tab id="3" top="794" row id="4" top="17121" fly id="8" top="16725" txt id="7" top="1394" fly ptr="0x6ce5510" id="10" top="1302" SwTabFrame::CalcFlyOffsets() detects an overlap with the large fly, and since it has wrap NONE it resizes to below the large image. Then the SwTabFrame doesn't fit on the page, so it is split, but the split fails because nDistanceToUpperPrtBottom is -720 (negative); hence it is joined again. Meanwhile the fly was invalidated, so now CalcFlyOffsets() ignores it and the table shrinks again. Once the fly is positioned again, the process repeats from the start. Fix this in SwTabFrame::CalcFlyOffsets() by ignoring flys with wrap NONE that extend below the body of the document and are anchored in a frame in the next-chain of the table frame: these must move to the next page with their anchor frame. For the bugdoc this gives the same layout as LO 5.2. Reportedly this problem started to happen since commit 6f5024de2e1a5cc533527e45b33d9a415467c48d, but it's not obvious why.
