The bug severities are defined in the context of all users, not just
some individual users. "Makes the package in question unusable" means
the package cannot be used on any system, which isn't the case here (or
there would have been many more reports about it, but there hasn't been
any other report).

Please provide the output of the following:
apt-cache policy libegl1-mesa
ldconfig -p|grep libEGL

Right, as expected the problem is specific to glamor, which is the
default for your GPU in 7.9.0 but wasn't yet in 7.8.0. This means in the
worst case you can work around the problem with
Option "AccelMethod" "EXA"
