Please, fix this stupid resolution bug asap. After patch game literally unplayable for me - all blurred, no window mode. Other resolutions are useless as well bcos picture stretched.
I had the Same Problem.
The UI looked terrible blurred in 3440x1440 and fullscreen and somehow "unusual small".
But i actually got a workaround that fixed it for me.
As long i had in the resolution option 3440x1440 and Fullscreen i could not change the Display Mode.
So changing the Resultion to 1024x768 re-enabled the Display Mode option.
Then go there and change the Display Mode to Windowed Fullscreen (ignore the Resolution).
Apply => I got a sharp 3440x1440.
