Package: xserver-xephyr
Version: 1:1.19.6-1
Severity: important

I use Xephyr to play Sid Meier's Alpha Centauri (yes, people still play that), 
and this requires disabling its Composite extension (or the game hangs). 
Unfortunately, on my amd64 machine with Xephyr version 1.19.6 this throws an 
error (used to work with version 1.19.5):

$ Xephyr :1 -screen 800x600 -extension Composite

>initialized' failed.

Fatal server error:

Withour "-extension Composite" Xephyr starts, but unfortunately I can't play 
the game. Given that this is the only reason I use Xephyr (and I suspect that 
applies to many people as well), I think this bug qualifies as "important"...
