No, but neither do you have an evidence that disabled backing store 
is usefull on xorg < 1.5.0. Well, there is a very little evidence 
that it may improve performance in some cases in the first mail of 
original tread in mplayer-dev ML.

It is harmful only for newer versions of xorg >= 1.5.0. We have not 
enough creditable data to talk about its usefullness or 
uselessness for older versions. Due to this fact I argue to leave 
things as is for old versions for safety measures and change it 
only for new versions of X server. IOW my proposition is just to 
add an appropriate configure check and #ifdef closure. I do not 
propose to remove this at all.

Best regards,
