Description:
Chromium 64's seccomp sandbox has an interaction from recent nvidia drivers where it blocks the driver's access to its device files. The fix for this is due in Chromium 65.

See https://bugs.chromium.org/p/chromium/issues/detail?id=817400

I suggest pulling in the patches from https://chromium.googlesource.com/chromium/src/+/6b1b6d3a8555075e23cca89335e855d55f35fba9
until Chromium 65 is released.
This task depends upon

Sorry, made a mistake. Chromium 65 is the one with the bug, and Chromium 66 is the one with the fix.

What do you mean by "slow"? The upstream issue only discusses readPixels() not working with newer nvidia drivers.

Included the patch in chromium 65.0.3325.181-5; would still like a clarification on the "slow" part in the title.

Thanks for the links, loqs.

Closing since there's a confirmation of the fix on the forums.
