angle_perftests flaky on chromium.perf/Android Nexus5X Perf

angle_perftests failing on chromium.perf/Android Nexus5X Perf

Builders failed on: 
- Android Nexus5X Perf: 
  https://build.chromium.org/p/chromium.perf/builders/Android%20Nexus5X%20Perf

It seems like this test is failing 20-30% of the time with timeouts. A few examples:

Something is happening that results in a timeout. This seems to have been happening for at least 200 runs (since Jan 10, where I see a timeout).

Benchmark owners, can you please investigate?

I'll take a look.
UniformsBenchmark.Run/gles_matrix fails for some reason. Either timeout or 32 bit vs 64 bit difference, as it passed on GPU.FYI bot.
Yuly the bots don't run quite the same tests - they only do one iteration and early exit to speed up the runs. If there's some kind of problem that only shows up with more iterations (memory leak, something of that kind) it will unfortunately only show up on the perf testers.
