A little bit of digging and I found to explain the difference in gradients. Basically, if the page is 100% opaque, the gradient appears. If not it won't. On ru.wrframe the opacity if 0.95, and on ru.mlp the opacity is 0.92.

Chances are the discrepancies in "strings" is down to similar conditional styling - I'd be surprised if it was due to a subtle bug in how it's all bundled together.
