Can you verify that the rectangle is in fact not a new top-level
window but an in-window artifact of SDL by logging window mapping
requests in your X11 server.

Something like the following Pseudo-C snippet, or preferably a gdb
trace, should do the job.
| case MapRequest:
| fprintf(stderr, "XID:\t%i", Req->Window);
| break;

The XID, if it's a top-level window, can than be input as an argument
to xprop or xwininfo.

You're most likely not, this seems quite bizarre.
