@a2_4am @thomasfuchs Huh! Did you install from github, compile yourself, or Homebrew? I've done Homebrew and compiled myself and both have worked for me (M1 MBP, OSX 13.3). I think the problem with dual monitors is related to the screensaver rather than the HTML, so I'm thinking of taking a run at the screensaver code but no promises there. Freshly compiled with latest Xcode on new OS didn't magically fix it…
