I will some (partly conjectural) ideas relating the following topics: (i) Smith-Treumann localization for sheaves on affine flag varieties; (ii) Kazhdan-Lusztig cells and $p$-cells in the affine Weyl group; and (iii) cohomology for (higher) Frobenius kernels. This talk is based on joint work in progress with R. Bezrukavnikov, P. Boixeda Alvarez, and S. Riche.
