Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hi,
I recently found my GPU struggling to render simple websites on icecat while
ungoogled-chromium is able to do it correctly.
The most recent one was element, Matrix's web client.
I opened an issue there[^1] and they told me to set the `gfx.webrender.all` to
`true`.
I did it and everything worked like a charm, and the rendering effort for any
other website went down significantly.
Why do we ship icecat with this variable unset? Can we set it so more people
benefit from the new rendering engine?
Thanks,
Ekaitz

Seems this feature is rather new, and has been (is being?) deployed to
selected systems by Mozilla. Given that Icecat is based on the ESR (the
slower paced Firefox releases), it'll probably take a little while to
land.
You should dig more to get a definitive answer though! Perhaps the
Mozilla folks would know best.
Thanks,
Maxim

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?
Thank you,
Maxim

I'm closing the issue, as I don't think it's Guix responsibility to
decide whether Icecat should deviate from the upstream Firefox (ESR)
version it is based on.
Thanks,
