Bug report #789
QGIS has a "hole" in my SHAPE file
|Affected QGIS version:||Regression?:||No|

|Crashes QGIS or corrupts data:||Copied to github as #:||10848|
The attached SHAPE file is not shown correctly in QGIS. The polygon with an attribute MU equal to 31 is black and cannot be symbolized, I tried to symbolize it using the MU and the SEC_NAME attributes and it was shown in black in both cases.

Any progress on the testcase shape?
I emailed the data to Gary hoping that he could attach it but it is not here. Can you attach it if I email it to you? If so then just let me know where to send it, the zip file is about 700kb. Unfortunately I don't even have an FTP server to put it on.

The file is at http://www.norbit.de/~jef/ForestManagementUnits.zip until this bug is fixed.

This works for me correctly (kubuntu linux, 0.9.1 svn). I need to test it on windows later in the day.
after Jürgen said the same thing I tested it on three more Windows XP systems, all differently set up and got the same results, namely reproduced these problems (this ticket and Ticket #820).

Oh, I can reproduce it now. You are right, it happens if antialiasing is not enabled in the options dialog. This a most likely a Qt bug, so I'm closing this ticket. As a short-time workaround, you may enable antialiasing (Settings -> Options -> Rendering -> Make lines appear less jagged at the expense of some drawing performance). The map looks also nicer then.
