Please attach a (reduced) test case (Inkscape SVG file - before|after) - a screenshot does not really help to further investigate this on other systems - and also provide details about the chosen settings of the paint bucket tool (I fail to decipher them on the downscaled screenshot).
Keeping status as 'Incomplete' for now.
