Steps to reproduce the problem:
1. Have a host with two displays of unequal resolution width (2560 vs 1920)
2. Connect to Win10 host using Chrome Remote Desktop from Dell 13 Chromebook
3. Receive only a blank white screen in the client.

What is the expected behavior?
Both displays should be visible in the client.

What went wrong?
Chrome remote desktop displays only a blank white screen. Mouse and keyboard appears to control host, although not as smoothly as normal.

Did this work before? N/A

This issue does not occur when using an Asus Flip Chromebook (minnie) or when using the OSX client. I have experienced this only with the Dell 13 running either the i3 or 3205U.

The issue is somewhat mitigated by arranging the displays vertically instead of side-by-side, however, in the vertical arrangement the viewport autoscrolls to the top left when the mouse is released. 

Also, if both displays are set to the same resolution, the issue is resolved. However, running one monitor at suboptimal resolution is a workaround at best.
