For non- working webgl this is probably a little bit more serious. On current google-chrome-unstable on a fresh profile with default settings gpu acceleration is enabled. When it is manually enabled via chrome://flags and checking "Override software rendering list", this has happened at least since one or two stable versions, probably always. Symptoms: $ google-chrome-unstable ATTENTION: default value of option force_s3tc_enable overridden by environment. ATTENTION: option value of option force_s3tc_enable ignored.

With (dri3) offloading to a radeonsi GPU all the gpu stuff works. But directly running it on intel doesn't.

With dri3 temporary files are created with O_TMPFILE. The chromium sandbox does not allow creating temporary files with O_TMPFILE. So another workaround for now is to use chromium/chrome with the --no- sandbox option (which will possibly reduce security). There's a corresponding bugreport at chromium that was not publicly visible before, but now is: https://code.google.com/p/chromium/issues/detail?id=415681#c9 Close this with NOTOURBUG/WONTFIX?
