I have a problem running a Gtk program when using the "Qt" style as supplied via gtk-qt-engine and kde-config-gtk-style.
The program is a fairly heavy duty computation that uses openmp for parallel computation and has a gtk progress monitor (which is updated from within a "critical" section so it can never be accessed by more than one thread at a time). When the "Qt" style is selected, the progress bars (gtk_progress_bar) are corrupted and the errors below are displayed repeatedly: (th_run:2015): Gdk-CRITICAL **: gdk_pixmap_foreign_new_for_display: assertion `(anid != 0)' failed (th_run:2015): Gdk-CRITICAL **: gdk_draw_drawable: assertion `GDK_IS_DRAWABLE (src)' failed (th_run:2015): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed QPixmap: It is not safe to use pixmaps outside the GUI thread QPixmap: It is not safe to use pixmaps outside the GUI thread QPainter::begin: Paint device returned engine == 0, type: 2 QPixmap: It is not safe to use pixmaps outside the GUI thread QPainter::end: Painter not active, aborted The problem does not occur with other Gtk style settings (e.g. Nuvola). I'm not sure if the problem is with the Qt wrapper, Gtk+ or my code. FWIW I'm running Debian stable, with Gtk+ 2.20. Any ideas?
