Predator and CL could not provide any possible suspects.

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

Suspect CL: https://chromium.googlesource.com/chromium/src/+/3689f3e57b85ca683cc6b61841715fbd0c6af559

kbr@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!
