Can only see total instructions and branches go down
without cache misses going up (according to perf).

linux_aura: Fix drawing of the bookmark bubble in High Contrast Inverse.

We weren't updating colors correctly in the bubble, and were hardcoding
the button colors in a way that we shouldn't on Linux.
