Hmm, that's a good point. So if you've double-checked that the driver is
flushing properly in the BlockHandler, and there's still no timeout interval in
exaDamageReport_mixed which provides a better tradeoff between latency and
throughput, let's leave it at that for now.

However, then the question remains what is the cause of the '[...] not
displayed until I generate more output or update some other part of the screen'
in this report. That doesn't sound like something your EXA change would help
