To reproduce this bug, play the "Weather" video at http://www.bbc.co.uk/weather using Firefox and Adobe's flash-plugin-126.96.36.1993-release.x86_64. Ensure that "Hardware acceleration" is enabled, and then enter "Full screen" mode.
On my PC, this results in a black screen with a small, blank rectangle in the top left corner. And then the flash plugin will crash a few minutes later.
This does not happen with either i965 (Broadwell) or r600 (HD6450) hardware. Nor does it happen with Chromium and chromium-pepper-flash-188.8.131.52-1.fc24.x86_64 with my R7 360, although chromium-pepper-flash doesn't appear to use libvdpau_radeonsi.so either.
