--- Comment #10 from Wim Lewis <wiml at hhhh.org> ---
(Continuing this bug report from
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=767356)

I rebuilt with --enable-debug and got this output. I'm not sure what info is
useful, so I'm also attaching a file with stack traces from the places where
att_incomplete() was called.

(gdb) set env MESA_DEBUG=incomplete_fbo
(gdb) set env GLAMOR_DEBUG=1
(gdb) set env EGL_LOG_LEVEL=debug
