--- Comment #4 from lightonflux <l-libreoffice at znn.info> ---
I did some further testing and ran sysprof. While scrolling the CPU usage hits
100% on one core.
When looking at the recorded time frame in syslog i see 12k hits for
libfontconfig.so.1.12.0. Which is 87% of all (recorded) function calls in the 5
sec time frame. 

See screenshot 5sec-scrolling-sysprof.png. I also attached the complete
recording.
