On =www-client/chromium-58.0.3029.81, the following is listed on chrome://gpu Graphics Feature Status Canvas: Hardware accelerated Flash: Hardware accelerated Flash Stage3D: Hardware accelerated Flash Stage3D Baseline profile: Hardware accelerated Compositing: Hardware accelerated Multiple Raster Threads: Enabled Native GpuMemoryBuffers: Software only. Hardware acceleration disabled Rasterization: Software only. Hardware acceleration disabled Video Decode: Software only, hardware acceleration unavailable Video Encode: Hardware accelerated VPx Video Decode: Software only, hardware acceleration unavailable WebGL: Hardware accelerated WebGL2: Hardware accelerated On =www-client/chromium-60.*, WebGL2 is disabled, and a bug relating to radeon graphics cards is cited in "Problems Detected" below. However, on my system I have VIDEO_CARDS="intel" (only using intel graphics, no drivers for the radeon card). The issue is fixed by downgrading to =www-client/chromium-58.0.3029.81 and changing no other packages or files.
