[QScintilla] QScintilla folding display issue with Qt4 (did not exist with Qt3)

[Gilles Depeyrot]

Hi,

We are porting a cross-platform application from Qt3.3.8 to Qt4.4.3
which uses QScintilla 2.3.2.
A class of our application inherits QsciScintilla, and uses the Folding
functionality.

A problem has appeared in the Qt4 version of our application that does
not occur in the Qt3 version:

  - the display of the folding margin is not correct (screenshot
attached) under Linux, while it is correct under Windows.

This display problem occurs even if there is no lexer.
We have tried updating to QScintilla 2.4 but the problem persists.

Any hints as to what might be causing this behavior?
Are there additional initialization steps that should be performed for
QScintilla with Qt4 that were not needed with Qt3?

Best regards,
Gilles
