Testing with rev 8787908e and KiCad Version: (5.99.0-11678-ga208dac8d8), I'm reliably running into the via stitching tool stitching my ground plane right into the middle of pads that are very much not supposed to be connected to ground.
I've attached both a screenshot showing the issue and a minimalish test board that one can use to reproduce the issue. To get this exact layout to generate the output seen in the screenshot, I'm leaving all the settings at their defaults except setting the Via grid to 1cm, but I've also seen it happen with the default settings.
I'm happy to answer questions about this bug report or to test out a proposed fix.
