Hi,

When using the DrawString methods on IDirectFBSurface, sometimes some (or all) characters of the string are not rendered. When DrawString is called again with the same text, it is rendered correctly. When stepping through the directfb code with the debugger or enabling tracing everything works, so I suspect a synchronization issue. I'm using the X11/GLX backend with the gl driver on DirectFB 1.4.7 and FT2 for font rendering. Any ideas about what this could be or how to pinpoint the root cause would be most welcome.

Kind regards,
Martijn Wijns
