I can reproduce this issue on r257841 using the command below. --iterations 2000 --exit-after-n-failures 5 --force -f fast/hidpi/image-srcset-relative-svg-canvas.html --no-retry [1/2000][4/2000] fast/hidpi/image-srcset-relative-svg-canvas.html failed unexpectedly (reference mismatch) [17/2000] fast/hidpi/image-srcset-relative-svg-canvas.html failed unexpectedly (reference mismatch) [18/2000] fast/hidpi/image-srcset-relative-svg-canvas.html failed unexpectedly (reference mismatch) [19/2000] fast/hidpi/image-srcset-relative-svg-canvas.html failed unexpectedly (reference mismatch) [25/2000] fast/hidpi/image-srcset-relative-svg-canvas.html failed unexpectedly (reference mismatch) Exiting early after 5 failures. 22 tests run. 17 tests ran as expected, 5 didn't (1978 didn't run): Same command on r257839 gives this result: All 2000 tests ran as expected.
