Selecting objects slow when fill/stroke dialog is visible (Windows 10)

Steps to reproduce:

  1. Open Inkscape 1.0
  2. Draw shapes with fill and stroke
  3. Select one shape, then the other (note the speed of selection)
  4. Open Fill/Stroke dialogue
  5. Select one shape then the other (note how much longer it takes for selection handles to appear

What happened?

Selection is notably slower: takes a full second to select a shape, when before (without fill stroke dialogue) it takes a fraction of a second.

Closing the fill/stroke dialogue fixes the speed problem, so it's definitely the culprit.

...

What should have happened?

selection should take a fraction of a second, always, regardless of which dialogues are showing.
