Thanks, that's extremely helpful!
Indeed, that's exactly what I see when I check the positions with a Writer
paragraph selected in Accerciser:
> In [82]: acc.queryComponent().getPosition(pyatspi.component.XY_SCREEN)
> Out[83]: (1989, 415)
> In [83]: acc.queryComponent().getPosition(pyatspi.component.XY_PARENT)
> Out[84]: (19, 113)
> In [84]: acc.queryComponent().getPosition(pyatspi.component.XY_WINDOW)
> Out[85]: (19, 113)
> In [85]: acc.queryText().getCharacterExtents(0, pyatspi.component.XY_SCREEN)
> Out[86]: (2065, 415, 12, 19)
> In [86]: acc.queryText().getCharacterExtents(0, pyatspi.component.XY_PARENT)
> Out[87]: (76, 0, 12, 19)
> In [87]: acc.queryText().getCharacterExtents(0, pyatspi.component.XY_WINDOW)
> Out[88]: (76, 0, 12, 19)
I'm working on a fix.
