The laptop has a Radeon , a 550X I think, but I'm not sure I'm actually
using it; it might be using just the built-in Intel one.
Either way, I was having bad problems using OpenGL as the backend, as
When using the DisplayLink hub, it would get super glitchy visually,
like 80s TV loss of sync. Going to Xrender fixed that, and I hope it's
not the cause of this one. I guess I can script something that switches
between OpenGL and Xrender depending on whether I'm docked or not.
In a variation of the Streetlight Effect, I'm going to try the other
suggestions first, but thanks for the heads up.
