> I was able to apply a gaussian blur to a circle and drag it around
Sorry, bug #886795 is about rearranging filter primitives in the filter editor dialog, not about dragging (filtered or unfiltered) vector objects on-canvas. Please don't spend additional time with trying to reproduce it unless you want to dive into custom filter effects in Inkscape anyway ;-) - bug #886795 is just another rather recent drag&drop-related report I recalled to be only occurring with KDE / oxygen-gtk too, and otherwise not directly connected to the problem with the guides/rulers reported here.
