QFileDialog very slow with GTK3

  • I have the following problem, and as far as I can tell, it is linked to GTK3. If you do this:

    @QStringList files = QFileDialog::getOpenFileNames();@

    And select a bunch of files, then function returns fast, but the dialog box stays there and block any user interaction for a long time, which seems proportional to the number of files selected. The problem disappears if you use the Qt dialog box, and it doesn't happen with GTK2 either.

    What can I do?
