I started experiencing this issue with Mint 18, with the Oibaf ppa enabled.
Mint ships with xserver-xorg-video-ati 1:7.7.0-1, so I was able to track down
the issue from there using the source from the official repo. I traced it back
to commit 1181b9c582f10b6c523e4b2988e2ce87ecf3d367 but as far as I can tell,
this commit pretty much just enables DRI3 on this device:
( xserver-xorg-video-ati 1:7.7.0-1)
[ 9837.338] (==) RADEON(0): DRI3 disabled
( xserver-xorg-video-ati 1181b9c582f10b6c523e4b2988e2ce87ecf3d367)
[ 4355.160] (==) RADEON(0): DRI3 enabled
dmesg shows errors like <a class="bz_bug_link
bz_status_RESOLVED bz_closed"

both of which are only present when this or future versions are installed.
