Chrome on android not unaffected

more relevant error message:
03-25 16:43:37.398 23319 23349 E chromium: [ERROR:gles2_cmd_decoder.cc(14640)] [GroupMarkerNotSet( crbug.com/242999 )!:54220A98]GL ERROR :GL_INVALID_OPERATION : glCreateAndConsumeTextureCHROMIUM: invalid mailbox name

This would be on the parent compositor, android render thread end

Broken only for component build I think o_O

My regular local build with gn:
is_component_build=true
is_clang=true
use_goma=false

I flipped these three, and the resulting apk works.

I'm suspecting that the globals in MailboxManagerSync somehow isn't global anymore o_O

Yeah, the static MailboxManagerSync::TextureGroup::mailbox_to_group_ variable has different address on the producer and receiver ends.

How this can actually happen and the build is still successful is beyond me..

For webview, two MailboxManagerSyncs are created from two different components:
content/common/gpu/gpu_channel_manager.cc
gpu/command_buffer/service/in_process_command_buffer.cc

So then my theory is that gpu sources (including MailboxManagerSyncs) is now built twoce, into the content shared lib, and whatever shared lib in_process_command_buffer.cc happens to be in.

Yeah, afaict gpu/command_buffer/service and gpu/config was built twice in component build. Once into the content shared lib, and once into the gpu shared lib.

I'm not sure why original CL had to depend on the source targets rather than the targets themselves. Latter seem to work for me fine: https://codereview.chromium.org/1838493002
