Darkroom mode not working

  • Hi, I have a problem with darkroom mode, it simply doesn't work. I could guess that this is connected with Windows 10 May Update, but i'm not 100% sure.
    I checked current version (4.104) and beta (4.105), both don't work.
    Also, most color effects seem to be buggy or not working.
    I've got 18362.145 installed.

  • I've got the exact same problem, can't use the dimming feature as well. It's because of the latest 1903 windows update, nothing else. Hope this gets resolved soon!
