The original change causes a large tscrollx linux64-shippable-qr regression, we'll have to revisit this after we better understand the regression.

Did you try setting it to 256 to see what impact that has on talos? I'm wondering if it's a progressive increase or if we're hitting some cliff somewhere.

I'll get back to experimenting with this when I have less things to deal with in parallel.
