Merge lp:~vanvugt/mir/fix-1576690 into lp:mir

[Daniel van Vugt]

Fix failing acceptance test:
ClientLatency.triple_buffered_client_has_less_than_two_frames_latency
(LP: #1576690)

Technically we expect exactly two frames latency when triple buffering
and no early release. We see that on regular machines, but CI is often
too loaded to stay at two frames latency and yields ~2.6 instead. So
accommodate slow machines without weakening the test too much.

[Daniel van Vugt (vanvugt)]

The failures are unrelated to this branch.

One third is:
https://code.launchpad.net/~vanvugt/mir/fix-1583970/+merge/295294

One third is:
The CI machine only achieving 1.4 FPS when we fake-render at 10 FPS. Possibly beyond help :P

One third is:
nbuffers expected to be 3, but measured to be 2. This might be one of the NBS regressions kdub is about to land a fix for. In theory the test should always hit 3 buffers because it renders in bursts that flood the queue.

I'll log new bugs and see if they reoccur. But seriously, if the CI machine can only manage 1 FPS, we need to restructure CI. Because that means there's no way to automate performance testing by any name.

[Daniel van Vugt (vanvugt)]

Bug 1583970
Bug 1584605
Bug 1584603

One has a fix already. The other two I will need to work on more workarounds for.
