MigrateToActiveGPU is only called on compositor GLContexts, not for WebGL. See bug 1597547 for WebGL. After this fix, the situation can be improved in multiple ways: - Rather than moving contexts between GPUs, it would be better to have separate contexts for each GPU, and teach our compositors to switch a window over to a new context. - Instead of creating a fresh context to obtain the "preferred" GPU, we should find the GPU that drives the display on which the context's results are going to be displayed.
