Comment 4 for bug 1352631

The issue here is that accelerated canvas is currently blacklisted on Chrome Linux because of driver bugs. In order to enable it safely at runtime on specific hardware, we need to implement support for gathering GPU info to feed in to the GPUDataManager, and then we need to modify the GPU blacklist to enable it.

But the description is still not clear to me. I did ask for some more info on IRC a while ago - it's not clear from the description whether this bug is just about accelerated canvas not being enabled, or whether it's also saying that it doesn't work properly when it's enabled anyway
