A multipolygon is inverted in ST_AsMVTGeom in some cases

Description
A complex multipolygon is inverted (areas in the tile not in the multipolygon become multipolygon and vice versa) when preparing a tile.
The problematic multipolygon is attached.
I'm using the command
SELECT ST_AsMVTGeom(ST_Transform(problem.geom, 3857), TileBBox(12, 2358, 1093, 3857), 256, 10, TRUE) geom INTO test FROM problem WHERE ST_Intersects(TileBBox(12, 2358, 1093, 3857), problem.geom)
TileBBox is a function
create or replace function TileBBox (z int, x int, y int, srid int = 3857)
returns geometry
language plpgsql immutable as
$func$
declare
max numeric := 20037508.34;
res numeric := (max*2)/(2^z);
bbox geometry;
begin
bbox := ST_MakeEnvelope(
-max + (x * res),
max - (y * res),
-max + (x * res) + res,
max - (y * res) - res,
3857
);
if srid = 3857 then
return bbox;
else
return ST_Transform(bbox, srid);
end if;
end;
$func$;

I'm sorry, the SELECT was wrong, it should be
SELECT ST_AsMVTGeom(
ST_Transform(problem.geom, 3857),
TileBBox(11, 1180, 547, 3857), 256, 10, TRUE)
INTO test
FROM problem
WHERE ST_Intersects(TileBBox(11, 1180, 547, 3857), problem.geom);
and I just upgraded my GEOS:

This comes from the issues that geos has clipping geometries using the fast and dirty lwgeom_clip_by_rect, and although I made an attempt to fix it in https://github.com/postgis/postgis/commit/35db4ea0c0b02b15090f1e916c8fdb8ff6c5cc22 (done for #4183) it doesn't work for this polygon.
Coincidentally, as part of https://github.com/postgis/postgis/pull/356 I decided to switch the function order and clip the geometry after transforming it into mvt coordinates (instead of before). This should make it more robust but it still won't be bulletproof; the underlying problems in GEOS will still be there, but I don't think they will pop as often as there won't be points as close to each other after snapping them to the grid.
You can see the current output and the output with the change in the mvt_bug.png image attached above. I guess that change is interesting for older releases, so I'll try to separate it from the introduction of the alternative library (for clipping and validation) and backport it to 2.4 and 2.5.

Note: mvt_bug.png shows brown for current (invalid) output and green for new (and valid).
comment:6 by , 6 years ago
Another side note: the current output also shows another bug I saw recently (and addressed in that PR), which is the polygon having float values (31 81,229 79,224.333333333333 76.6666666666667,229 80,231.5 82.5)).
This has an even harder solution since the quick way, which is snapping to grid after validation, means that the polygon could be invalid again so you'd have to redo the make_valid call -> grid -> valid -> grid... This doesn't happen with wagyu (which only works with ints), but the default GEOS based solution would require a major effort to solve this.

Just to note that I've been testing Geoserver for this dataset too and its vector tiler (java-vector-tile, after upgrading to 1.3.4) does not have problem with this multipolygon. java-vector-tile uses JTS. Its result is:
