What steps will reproduce the problem?
I use a dual monitor setup with eyefinity stretching the display across both at a resolution of 3240x1080.  After updating, when I open viewport it automatically renders to 2880x1080.  When I adjust the rendering area to 1920x1080 it just squeezes the area down.  Also, trying to mouse over anything ends up being in the area it would be if the rendered area was 2880x1080.

What is the expected output? What do you see instead?
Rather than being able to adjust the rendered area down to 1920x1080 and still holding the correct aspect ration in the game, it automatically adjust to 2880x1080 and any other adjustments just skew the visuals.

What version of the product are you using?
Updated today to 7.0.3.0

Do you have an error log of what happened?
No

Please provide any additional information below.
I have screenshots showing the 2880x1080 and 1920x1080 views and will upload those too.
