   On Arm Mali libgles.so is both the opengl and vulkan driver

   Ah, okay. My theory is probably wrong then.

   So the first commit where it started crashing was:

   https://flutter.googlesource.com/mirrors/flutter/+/1333e16a4a1237fcc026dac844a29e4566368fa8

   So that is probably "stencil buffer record/replay instead of MSAA storage". We should check if we can repro locally. The big change from that commit is the benchmark is running a lot faster, which in theory could trigger other bugs - but it could also have to do with the transient stencil changes too.

    This test is no longer flaky. I suspect when @jason-simmons rolled the vulkan deps and fixed the queue submit validation error this problem went away, the timing seems approximately correct
