Public bug reported:
This pertains to the hwacc branches of snap_from_source chromium builds.
Following the guide-0.9.1, we switched from system gbm to minigbm.
(These switches are in args.gn)
use_system_minigbm = false
use_intel_minigbm = true
use_amdgpu_minigbm = true
This enables us to better support intel hardware.
However, there seems to be a regression on other gpus.
Chromium will switch to software compositing on amd.
When I revert back to system gbm, I get hardware compositing again.
See attached screenshot.
To reproduce: build chromium in two different ways, and compare the
output from the chrome://gpu url.
tested on: Radeon RX580 GPU.
** Affects: chromium-browser (Ubuntu)
Importance: Undecided
Status: New
