Mayavi undesired blue-red channel switch over VNC

Question

I'm experiencing an issue where the R and B channels are swapped in Mayavi figures.

I'm connecting to a remote machine (machine 2) via VNC (vncserver yields DISPLAY=:1, so I'm connecting to a newly allocated X session [?]) and running mayavi 4.4.3 on that remote machine.

Below is an example. Plotting a figure with bgcolor=(1,0,0) yields a blue figure (middle figure), (0,1,0) yields a green figure (right figure, expected), and (0,0,1) yields a red figure (left). (Ignore the beige, which was due to dragging the figure windows above one another)

I've tested this on my local machine (machine 1) with mayavi 4.1.0, and gotten the expected results of a red figure from (1,0,0) and a blue figure from (0,0,1), so the issue may lie with the remote machine. Again, the remote machine's Mayavi version is 4.4.3. Additionally, I've tested this on my local machine (machine 1) over VNC from a separate server (machine 3), and gotten the expect result, so it appears it can render correctly over VNC. I've also tested on machine 2, the problem machine, locally, with DISPLAY=:0 (the original display), and the problem is not present.

Here's an additional example of creating a Figure and plotting a point
