Hello, I will give the new version of XxU credit for crashing instead of freezing my machine (Debian 12 Linux, as a reminder), but it still does not work without manually disabling dither. However! I think because of this change (or maybe I never noticed it before...), I found a log file I can upload here in the same area as preferences.cfg: https://drive.google.com/file/d/1pvHDgblMVEmekKPOvyfR2r01cIVKiDfg/view?usp=drive...
Oh, also, I should mention that I deleted the "XxU" folder preferences.cfg is in before running the game and getting this log, in order to test a "fresh" experience.
