    Description

      Hi all,

      I have some probelms. Recently, I upgraded qt version to 5.3.1 and segmentation fault occured when running two examples at the same time(affine, imagecomposition).

      • gdb lnfo
        Using host libthread_db library "/lib/libthread_db.so.1".
        Core was generated by `./affine'.
        Program terminated with signal 11, Segmentation fault.

      I also want to know about qpa directfb support plans in the qt 5.4 or 5.3.2?

      the current qpa directfb platform have some problems(this issuue, touch/mouse event focus( + create unused window)).

      Thank you.
