Re: Bug with filled rounded rectangles?

[Michael Ross <michael e ross gmail com>]

Now that you mention anti aliasing - I have Dia using some outline text that makes horizontal, rightward going, white (or background colored) lines that mask other shapes stripey-like.  If I disable anti aliasing it goes away.  But hen the anti aliasing d\goes away which is disappointing.  I have the newest stable Dia on a Win7 machine.

I can verify this for Dia 0.97.1 on Windows, but not on Linux,
neither with the 0.97.1 nor the 0.97.1-git build.

That bug seems to be already fixed, the current source does contain
the suggested change.

- From what i can see on Windows this seems to be a rounding issue
with the top/left "rectangle" coordinates or arc sizes/position. The
artifacts appear/disappear with different sizes of the rectangle. As
far as i can see, the dia function is correct.

It seems that both artifacts disappear if anti-aliasing is activated.
Andrzej, could you confirm this?

I would assume this to be a gdk related issue, however i do not have
a windows development machine available to confirm this.
