My setup is three 1920 x 1080 screens, in a symmetrical pattern. When I select the larger, bezel-corrected, resolution in DCS, the graphics just shift across, as you describe. 1.2 works perfectly in this respect.
I have played with the monitor LUA file and various resolutions but have never managed to find the correct setup.
Like you, I don't want to have to play without the bezel correction - it just looks weird.
