With recent build of libdrm (2.4.93) Mozilla Firefox cannot us=
e accelerated
WebGL, use software emulation instead.

HW. AMD RX560 and AMD WX2100 (RX550).

SW. Ubuntu 16.04 with kernels 4.17.X and 4.18.rc from
http://kernel.ub=
untu.com/~kernel-ppa/mainline/, plus Oibaf's PPA builds of drm,
mesa, etc. https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

Symptoms. Firefox works OK, but on site with WebGL it works very slow - due=
 to
fallback to software GL rendering.

Note. about:support page in Firefox DOES show correct driver info:
WebGL 1 Driver Renderer X.Org -- AMD Radeon Pro WX2100 (POLARIS12, DRM 3.26=
.0,
4.18.0-041800rc6-generic, LLVM 6.0.1)

But, on WebGL site (ex. windy.com), swrast_dri.so get loaded and eats all C=
PU
cores.
