Xorg goes to infinity loop (delta = 548.33340590666785 and incr = 6.3659874129151343e-314). Chromium authors code not good.

But why scroll increment so small, I don't know, and in this moment mouse scroll not used at all.

"increment" is initialised once by the driver and that's where the server checks for and invalid increment of 0. it's read-only after that. This bug happened because of invalid memory access, there is only so much one can do against that.
