Note that actual 3-dimensional textures are not supported in the Compatibility rendering method yet: https://github.com/godotengine/godot/issues/71029

Your project doesn't appear to use any though, so this is likely an issue with VRAM compression formats. I suggest changing the compress mode from Video RAM to Lossless for your PNG texture in the Import dock though, as pixel art textures don't benefit from VRAM compression.

How do I reimport all textures? Do I have to do it one by one?

Tried to set one png to lossless then "Preset" > "Set as Default for Texture2D" but it doesn't seem to do anything.

Filtering *png in FileSystem docker then selecting all png, setting lossless and pressing re-import doesn't change compression mode to lossless either, it's still Vram Compression.

Select texture(s) in the FileSystem dock, go to the Import dock, change the compression mode and click Reimport. You then need to export the project again to see the changes.

Setting the default preset will not affect imported resources retroactively. It only affects newly imported resources.
