Did a full custom controller mapping as none of the community ones were all that good.

Some transparent textures darken the surfaces behind them; they shouldn't do this. Not sure if it's a Proton issue or happens in Windows as well, though.

The comptalk hacking minigame requires slightly more precise mouse movements than the trackpads can provide, meaning you'll need a wireless mouse to actually succeed at them.

There are a couple of issues involving a sequence a couple of hours in where you trail a suspect: the autosave mid-way through the trail deletes your photos if you load it (you can restore an earlier save, where they'll be intact, but it renders this specific save useless) and completing the trail will sometimes cause the cutscene that follows it to freeze. Closing and restarting the game, repeating the trail, then letting the cutscene play again will suddenly work.
