Pixel animations jitter after project is exported to another device

Godot Version

4.2.1

Question

Hello all,

Issue:
My 2D pixel art character animations look blurry (ie. I’m experiencing jitter) ONLY when playing on a Steam Deck via an exported Linux project. When I run my game on my PC - via an exported Windows project - there is not any noticeable blur with the character animations.

Thought it might be an FPS issue. But, I have my Steam Deck settings capped at 60 FPS. And, I confirmed the Steam Deck is running at 60 FPS while the game is running.

Screen recording is not included on Steam Deck, and I haven’t installed a screen recording addon to be able to share video of the jitter.

Facts:
-I have Project Settings → Rendering → Textures → Default Texture Filture set to Nearest.
-I have Project Settings → Application → Run → Max FPS set to 60.
-Animations are updated in the _physics_process.
-Player movement uses delta.
-My sprite texture is 32 by 48. But it’s scaled at 0.5 so is 16 by 24. Don’t think this related to the issue
-There is not a camera 2d node in the scene either.

Question:
Does anyone know how to resolve this, perhaps it’s related to monitor refresh? This is a bit out of my area of expertise

Thank you!
