Hardware Acceleration in Chromium using Debian

I’m trying to enable Hardware Acceleration and not getting results. I install OpenGL and the RockChip Mali Midgard drivers, but chrome://gpu either shows LVMPipe (virtualized GPU) or no acceleration at all. GLMark2 shows the GPU as available and scores the system. I’m using Chromium flags to force using the EGL and ignore the blocklist.

Has anyone been able to activate Chromium hardware acceleration? Am I missing a library or setting?

Bump! Any ideas from the community?
