The regression range was a bit weird, but i ran the regression twice and got the same range. Make what you will of this.

:jesup, since you are the author of the regressor, bug 1840516, could you take a look? Also, could you set the severity field?

For more information, please visit BugBot documentation.

That bug seems unlikely to have caused this regression.
Moving to webGPU for investigation.

Coincidentally, while doing bisection in Bug 1873047, I got the exact same bug as above. But when I checked the pushlog (https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=fec6b3b46bc6439ac98e03aa73938deaf6323f5c&tochange=ccf6a951de23c5f46d5ba5947caa0a2a2366ec1b) , it contained bug 1853140, which makes much more sense.

So I am going to mark this bug as a regression from bug 1853140

(I do not have authorization to remove the dependency from bug 1840516, so someone else would have to do so)
