 Can you explain how you downloaded the source for this build?
 I thought this should never happen, there should always be a useful
 version information...

 I believe that {{{--disable-stripping}}} is never a good idea, debug is
 the default.

 Please test if performance is better if you build with {{{--disable-libxcb
 --enable-x11grab --enable-gpl}}}.
