Description
I'm not sure why it happens, but rr fails with all applications using clutter.
The following code built with:
gcc clutter.c -o clutterapp pkg-config clutter-1.0 --cflags --libs
#include <clutter/clutter.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
clutter_init(&argc, &argv);
ClutterColor stage_color = { 0, 0, 0, 255 };
ClutterActor *stage = clutter_stage_get_default();
clutter_actor_set_size(stage, 512, 512);
clutter_stage_set_color(CLUTTER_STAGE(stage), &stage_color);
clutter_actor_show(stage);
clutter_main();
return EXIT_SUCCESS;
}
It fails to grab a GL context
(clutterapp:5165): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to initialize the Clutter backend: no available drivers found.
All other clutter apps I tried failed for what seems to be a related reason.

Research direction
Start with the provided clutter.c example and reproduce the failure using the documented gcc and pkg-config command, then run the resulting clutterapp under rr. Trace why Clutter cannot initialize a backend or obtain a GL context; done means the example and other Clutter applications can be recorded without the reported driver error.
