  • [x] that I have checked whether there are updates for my system available.

Symptoms

Dialogue text is blurry at 1280x720 resolution; other graphics are crisp so this is probably some kind of flag that needs to be set in the font thingy. Some menu text is also crisp, so it might be prerendered or rendered with different settings.

Reproduction

  1. Start the game on a Steam Deck.

Steam Deck screenshot (money in the top left is crisp, health is blurry, button prompts (not the icons but the text that explains what the button does) and character dialogue are even blurrier but I took the screenshot here because that's where it loads from the save)

Edit: Playing through the game some more, it doesn't seem consistent whether any specific piece of HUD text is blurry or not, but anything in a speech bubble (dialogue and button prompts like "hold to open store") is always blurry. The money/health being crisp/blurry is likely just getting lucky/unlucky with whatever the game uses to render the font. (Just mentioning this in case it helps track down the solution.)
