Thanks Darren! Acknowledgment was what I was looking for, I know you can promise an ETA but at least this way we know it's in a bug list that will be looked at and evaluated for future patches.
I have a 21:9 2560x1080 screen. My highest display option is 1920x1080, which causes essesive stretching. I tried manually editing the ~/.config/unity3d/Obsidian Entertainment/Pillars of Eternity/prefs file, but it immediately reverts to 1920x1080.
