            Bug ID: 128713
           Summary: missing grid pixels ...
           Product: LibreOffice
           Version: 6.4.0.0.alpha0+
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: major
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: michael.meeks at collabora.com

This is as discussed in:

https://gerrit.libreoffice.org/#/c/82221/

which (apart from the patch expanding the area in totally the wrong place -
should be after we check for empty or before the intersection) - seems to
rather help.

bin/run tilebench `pwd`/instdir/program
libreofficekit/qa/data/join/calc-100-textjitter.xlsx --join

with the patch:

        Zoom 0.5 bad tiles: 2 with 228 mismatching pixels
        Zoom 0.85 bad tiles: 1 with 171 mismatching pixels
        Zoom 1 bad tiles: 1 with 103 mismatching pixels

without the patch:

        Zoom 0.5 bad tiles: 64 with 1227 mismatching pixels
        Zoom 0.6 bad tiles: 64 with 1227 mismatching pixels
        Zoom 0.7 bad tiles: 64 with 1456 mismatching pixels
        Zoom 0.85 bad tiles: 64 with 1978 mismatching pixels
        Zoom 1 bad tiles: 64 with 2215 mismatching pixels
        Zoom 1.2 bad tiles: 64 with 2609 mismatching pixels
        Zoom 1.5 bad tiles: 64 with 3023 mismatching pixels
        Zoom 1.75 bad tiles: 64 with 4039 mismatching pixels
        Zoom 2 bad tiles: 64 with 4406 mismatching pixels

So ~all tiles are bad there I think. I attach a picture of the:

/tmp/dump_tile_diff to show the fun =)
