[Mono-winforms-list] Unexpected artefacts on WinForms porting

[Sylvain Lesimple]

Hi,

I did some additionnal tests that could interest you.

First, on my Ubuntu distro, a part of the problem disappear when I uninstall
mono 1.9 to mono 1.2.6. This manip permit to fix fonts issues but it don't
resolve missing borders.

Then, I installed the VMware openSUSE 10.3 which works with mono 1.9, and
any of the problems encountered in Ubuntu appear. The render is nearly the
same as with mono on Windows.

So, the last Ubuntu distro seems to be responsible for those problems.

Unfortunately, I'm not familiar with bug reporting and my time credits for
these investigations end today.
They maybe continue later.

Merci pour votre aide et bonne continuation.

Sylvain.
