Nice update it is effectively working.
But, the textures are sadly uglier.
As you said, all resolution use the same textures, so in 1920 we just got a "zoomed" version of the game.
It's a bit a shame, as I personally would prefer the resolution of the bug another way, so that the texture we should get on 1920 before would work (much nicer and proportional the the screen resolution).
Another glitch with this solution is that on 1920*1080 screen resolution, when you create a new character, you can't see the description of each classes. The window with the description just pop up a fraction of second and then disappear and never comes back.
Oh and btw, you said we shouldn't be able to change the screen size manually anymore, in fact I still can choose the screen resolution and mode (windowed or fullscreen). Did I miss something or misunderstood what you said ?
