    Unhappy Qt/X11 source-distro apps corrupting KDE Desktop background

    All -

    I am trying to fall back to an older distro of Qt than the Qt 4.5.1 that ships with Fedora 11 as a workaround a broken QtMySQL driver in 4.5.1 (http://www.qtcentre.org/forum/f-qt-p...295-22654.html) but am running into problems with my source distro built apps as follows:

    • Exposed KDE4 Desktop white(app moved)
    • Other apps when moved produce same effect while my Qt app is running
    • KDE4 Plasma workspace context menu will not display
    • Problem observed with Qt apps compiled from Qt source distros 4.3.4 and 4.4.3
    • All Qt libraries (listed via ldd) resolve to Qt distro libraries
    • Problem does not appear if Qt app rebuilt under Fedora Qt 4.5.1
    • Problem clears after a while. Background redraws, context menus work
    • Using latest nVidia driver. OpenGL enabled, have tested with X11 backing store turned on & turned off


    Any suggestions at all as to what might be happening?

    Thanks,
    Bill
