Perhaps the > Mozilla folks would know best. Turning such feature on in my version of icecat didn't seem to break something (or improve much) until I restarted it, at which point the output was totally garbled. That's using it with an nvidia 8800 GTS card and the nouveau driver. So, unless the upstream Firefox ESR GNU Icecat is based on has this bit turned on, I'd vote to close this issue. What do you think?
