        <pre>Hello,

Ever since upgrading from Ubuntu 14.04 to 16.04, and thus from Catalyst to
radeon, opening windows / games with opengl in them is possible, BUT I have to
resize the window in order to see anything.

I switch to the AMD card by using `DRI_PRIME=1`.

A simple test is running `glxgears` which renders a nice black window.
