Revert "exa/mixed: Exclude frontbuffer from deferred pixmap handling." 

This reverts commit 541b25038a.

- It turns out that the high latency was a driver problem.
- catting a large amount of text turns out to look prettier when the
  throughput is lower, but it's not worth the loss for a minor
  improvement that may not even exist on someone else's computer.
