Predator and CL could not provide any possible suspects.

Using Code Search for the file, "paint_op_buffer.cc" suspecting the below Cl might have caused this issue

I'm unable to reproduce this on Linux, either at ToT or at the revision that the reproduce tool syncs too.

It appears that somehow a canvas is creating an invalid rect.  Probably it's passing some sort of nan rect, but it could be invalid flags as well.

I wonder if we should should just drop all the isFinite() checks on rects if canvas can create these from Javascript.
