Pi Hardware: CM3+
OS: Latest 32-bit Raspberry Pi OS Bullseye downloaded today
Browser version: Chromium 101.0.4951.57 Built on Raspbian , running on Raspbian 11
On a CM3+, using dtoverlay=vc4-kms-v3d, and with Glamor enabled, the demo looks like this:
The speed at which the sprites move indicates the hardware acceleration pipeline is being utilized, but the graphics are just not rendered correctly.
Disabling Glamor, and adding command line arguments --use-gl=angle --use-angle=gl-egl --use-cmd-decoder=passthrough seems to work around the issue. The workaround does not work if Glamor is enabled, which is quite curious.
