This is a benign shader warning. We should at some point either figure out if this is an ANGLE bug, or is a case of undefined behaviour. If it is undefined, we can always fix the offending shader (likely a compositor or rasterization/Skia shader somewhere). Lowering priority since it isn't user-visible aside from the about:gpu page.

CC'ing Olli, who has a lot of expertise in the HLSL transpiler component of ANGLE.

I can no longer reproduce this in Canary. Olli did you inadvertently fix this warning with your integer pow workaround fix, or another CL?

I don't think the pow workaround fix should have affected this. Maybe the compositor or skia shader causing the issue got fixed?
Status: Fixed (was: Assigned)
Yeah, verified it's still happening.
