Hi! I can confirm that adding
--use-gl=desktop to /etc/chromium.d/default-flags makes hardware acceleration work (again) with chromium 87.0.4280.88-0.3 on unstable (on two systems with integrated intel graphics), according to chrome://gpu. NB: to get accelerated video decoding I had to also add --enable-accelerated-video-decode (but this is not a regression AFAIK, since it was not available at all -- at least not by default or using that option -- before). - Felix
