I have an alternative patch (no PPA, sorry), that replaces the backfilling of pixmaps with clearing them. Pixmaps with an alpha channel will be initialized transparent. Pixmaps without an alpha channel will be initialized black. That replaces temporary corruption observed with KDE menus with temporary black squares until the actual menu appears. Performance should be about the same as with the no-backfill patch but this one fixes the potential security issues of exposing random memory contents.
