These 2 telemetry test fail when SwiftShader is enabled:
benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.system_health.memory_desktop.load:tools:drive
benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.system_health.memory_desktop.load:tools:gmail
These tests are being run in a VM on the both and, currently, WebGL is turned off. When SwiftShader is available, WebGL is turned on and these tests appear to time out.
It is possible that the timeout simply need to take into account the extra time it takes to execute the WebGL code, which was previously turned off.
