<pre>Just as a first thought, this sounds very much like how the experience is when
one runs gnome-shell with a software rasterizer. Is there some log output from
sway that would prove it is HW accelerated? You could use strace to see which
dri module it opens (iris_dri.so, not swrast_dri.so) or for example gdb the
process and set break to iris_draw_vbo that should get called on each draw.</pre>
