Please describe your issue in as much detail as possible:

Turns out this game behaves differently on LCD Decks and OLED. On my OLED Deck in game mode, the game gets visually stuck on a black screen with loading text on the top left, but on my LCD Deck in game mode, it gets to the slime preloader with 0 issue. The bug seems to be purely visual as I can hear the sounds of slimes popping if you manage to click on one in the darkness.

Steps for reproducing this issue:

Start the game on an OLED Deck, then start the game on an LCD Deck and note the difference.
