I am trying to run Anki on one of my computers running the latest update of
CentOS 7. However, starting it in a terminal window shows it fails with the
following messages:

libEGL warning: DRI2: failed to authenticate
libEGL warning: DRI2: failed to open swrast (search paths
/usr/lib/x86_64-linux-gnu/dri:${ORIGIN}/dri:/usr/lib/dri)

Anki 2.1.15-alternate comes with the QtWebEngine and I have this app running on
two other computers running CentOS 7. Thus, not a general problem but probably
related either to the graphics driver on this system xorg-x11-drv-ati or some
configuration mismatch. It was suggested on the Anki support forum I ask in the
distribution forum since they had no explanation...
