PNG export does not incorporate pointilism filters of all objects

[Peter Bouillon]

Hello,

I am trying to export the SVG file "R01 Felsvorsprung.svg" (attached) to PNG, using the menu option "Datei / PNG-Bild exportieren" (the English probably is "File / Export PNG picture).

I am using exactly the presets shown in the screenshot "screenshot.png" (attached) - especially note that I am exporting the page, not the drawing, and that I have set 25.40 dpi, not 25.00 dpi. (Exasperatingly, these get reset to different defaults every d... time I do next to anything in Inkscape, even when just saving.)

Clicking on "Exportieren" (the English is probably "Export"), I get file "R01 Felsvorsprung.png" (attached).

Note from the screenshot that all the grass patches shown have filter "pointilism" set. I've circled thee of them in green, one of them in blue.
Note that the grass patch in the exported PNG file that corresponds to the blue circle has this filter set - so the filter seems to be exported in principle.
Note, however, that the grass patches in the exported PNG file that correspond to the green circles do NOT have this filter set.

I was expecting that _all_ the patches are exported just as shown on screen.

My setup:
I am using a 64-bit Windows 10 German edition.
My Inkscape version, as given in the Help screen, is 0.92.1 r 15371.

As stupid as this may sound, I've found out the following:

- The bug will SHOW UP at dpi factors that make the page exactly 720 px high.

- The bug will NOT SHOW UP at dpi factors that make the page 719 px or 721 px high.
