UE5.7 Windows 2D project now building on Steam Deck is behaving differently on some sprites on Z-axis

I have a couple of 2D games I started developing on Windows

They are working well and I have an orthographic camera and my sprites are at a different depth on the Z-axis so they overlap nicely

I have now moved over to Steam Deck for development (using pre-built engine 5.7.4) and a game when run (editor or outside), is showing some sprites clashing even though they are not on the same Z-level

It’s not the orthographic mode, as I have the same issue without it. Sprites flicker in front and behind each other

It’s all related to the Z-axis

Has anybody who is working on Linux got an idea why this is happening when it is fine on Windows?

Just saw similar issues with 2D sprites when importing on Linux in 4.6.1.

A lot of assets are now offset? It appears to be consistent for affected sprites as animations have the same weirdness across their frames.

Investigating this.
If I find anything out I’ll reply.

Same with this duck, but guessing he’s not clamped and is now mirrored too:
