413 and wide triple screen resolution
 

413 seems to be repeating the same problem with 412 when it comes to wide triple screen resolution. I'm at 3072x768 and while inflight everything looks fine, the menus are all horribly stretched. It's very difficult to create missions in the mission builders, and very difficult to see the planes in the arming window since only part of a plane appears in a narrow horizontal window. This wasn't a problem before 412: the menus would stay at 1024x768 and then automatically switch to 3072x768 inflight.

I tried a few different permutations in the [window] section of the conf.ini (changing the 0's and 1's), but so far, nothing seems to get the menu to NOT stretch.

Does anyone have any ideas?

I'm not an expert, but a "definitive" solution would be to add a windowed mode for menu and mission builder. I would like to see this or another fix as a single-purpose patch (such as 4.13.1).

So this isn't working as advertised?

(I don't have a triple setup)

No, unfortunately, it only greatly distorts the side views.
