What steps will reproduce the problem?
(1) Connect from a client that has devicePixelRatio = 1.6 to a Linux host

What is the expected output?
The screen resolution on the host is set to match the client size

What do you see instead?
The screen resolution on the host is slightly larger than the client size.

It looks like the problem is that the client client rounds DPI from 153.6 to 153, but doesn't scale the requested resolution according to that DPI.
