Screen scaling is broken for all resolutions except 1280x720 in windowed mode:
In full-screen mode in any resolution there's a white clipped border area on the right part and on the lower part of the screen and mouse inputs seem to be offset by the size of the border.
In windowed mode with resolution greater than 1280x720 same thing happens as in the full-screen case above.
In windowed mode with resolution below 1280x720 the game screen renders correctly (without any clipped areas) but mouse inputs are still off by some amount.
The issue is worse if i use a 1920x1080 external monitor (instead of the 1366x768 builtin display of my laptop).

I'm running the game with these options:
Here's the log: steam-335300.log
Here's my system's info. What's missing there is that i have a dedicated GT530m GPU on which i'm running the game using bumblebee.
I haven't tested other games on Steam Play so i'm not sure whether the issue is exclusive to Dark Souls 2 or not.
