QTabWidget: first tab's text not displaying

There's something wrong there, and the font doesn't seem to be antialiased.
Does that happen only for the first tab, or for the current tab?
Have you tried with an *actual* completely minimal code (just one or two
tabs with only a QWidget as their pages)?
If you allow moving tabs (btw, movable tabs are disabled by default, so
there's no need for that line), does the title appear in the drag object?
Are you using some generic stylesheet (with the "*" universal selector or
without any selector at all) applied on the application or parent window?
The title is there (if you use very high contrast on very low lightness
you'll see it), but considering the overall look I'm inclined to think
that's a specific platform/style issue (the ugly font might be a hint).
Can you provide more information about Linux distribution, window manager,
PyQt version, etc.?
What is the output of QApplication.style().objectName()?
