Arduino-Sketch:
--------------------------------------------------------------------
// Arduino "bridge" code between host computer and WS2801-based digital
// RGB LED pixels (e.g. Adafruit product ID #322). Intended for use
// with USB-native boards such as Teensy or Adafruit 32u4 Breakout;
// works on normal serial Arduinos, but throughput is severely limited.
// LED data is streamed, not buffered, making this suitable for larger
// installations (e.g. video wall, etc.) than could otherwise be held
// in the Arduino's limited RAM.
// Some effort is put into avoiding buffer underruns (where the output
// side becomes starved of data). The WS2801 latch protocol, being
// delay-based, could be inadvertently triggered if the USB bus or CPU
// is swamped with other tasks. This code buffers incoming serial data
// and introduces intentional pauses if there's a threat of the buffer
// draining prematurely. The cost of this complexity is somewhat
// reduced throughput, the gain is that most visual glitches are
// avoided (though ultimately a function of the load on the USB bus and
// host CPU, and out of our control).
// LED data and clock lines are connected to the Arduino's SPI output.
// On traditional Arduino boards, SPI data out is digital pin 11 and
// clock is digital pin 13. On both Teensy and the 32u4 Breakout,
// data out is pin B2, clock is B1. LEDs should be externally
// powered -- trying to run any more than just a few off the Arduino's
// 5V line is generally a Bad Idea. LED ground should also be
// connected to Arduino ground.

// A 'magic word' (along with LED count & checksum) precedes each block
// of LED data; this assists the microcontroller in syncing up with the
// host-side software and properly issuing the latch (host I/O is
// likely buffered, making usleep() unreliable for latch). You may see
// an initial glitchy frame or two until the two come into alignment.
// The magic word can be whatever sequence you like, but each character
// should be unique, and frequent pixel values like 0 and 255 are
// avoided -- fewer false positives. The host software will need to
// generate a compatible header: immediately following the magic word
// are three bytes: a 16-bit count of the number of LEDs (high byte
// first) followed by a simple checksum value (high byte XOR low byte

Edit the file
/storage/.xbmc/addons/service.multimedia.boblightd/bin/boblightd.start
On the bottom of the file there is a line that starts with "boblight-X11". This is the application that sends the stuff on the screen to boblightd. I don't know the original content of the line, but my line looks like
boblight-X11 -x -i 0.3 -o speed=50.0 >> $LOG_FILE 2>&1
I think the "-x" is the thing that removes the flickering. I read in the boblight sources that "-x" is also slower than the normal approach, but I cannot tell. Either my HTPC is too fast or the difference is not noticeable.
Be careful: If the boblight-Addon get's updated, your change will be reverted. So copy it to another location as a back up in case you need to restore it.
Another thing: Of course this only works if you are using boblight-X11. Using the other solution (that sends only XBMC's graphic output info to boblightd) this will not work.
