Re: Trying WebGPU samples on Chrome Canary on Windows 10

Thank you. I attempted to file
https://bugs.chromium.org/p/chromium/issues/detail?id=1021118 but it's
showing up completely blank for me, and I cannot even add someone to CC.
Not sure if I accidentally kicked the spamfilter or broke it by
pasting about:gpu, but the important thing seems to be this error:

[18768:9956:1104/092307.419:ERROR:shared_image_manager.cc(198)] :
SharedImageManager::ProduceSkia: Trying to produce a Skia representation
from an incompatible mailbox.
[18768:9956:1104/092307.422:ERROR:shared_image_manager.cc(198)] :
