Unity Scene视图瓦片渲染异常求助：仅编辑器内出现横向线条

Hey everyone, I'm stuck on a weird tilemap rendering bug that only shows up in the Scene view—it's totally fine in the Game view and when the game runs. Let me break down what's happening:

• When I look at my tilemap in the Scene view, there are horizontal lines all over the place (I've already turned off the grid overlay). Most of these lines are blue, which matches the water tile that's under my grass tiles; the pale yellow line next to the rock is from the sand tile underneath.
• The individual tiles look perfectly normal in the Sprite Editor—no artifacts there at all.
• This happens on my main PC and two different laptops, so I can rule out hardware issues.

Here's what my tilemap looks like:

And here are my tile palette references:

I've already tried several fixes that usually work for texture issues:

• Added all tiles to a sprite atlas
• Set the texture filtering mode to Point (no filter)
• Disabled texture compression

All the resources I've found online talk about texture bleeding issues that happen during runtime, which doesn't match my case since this only affects the Scene view.

If anyone has run into this before or has ideas on what to check next, I'd really appreciate the help! I can provide any extra details you need.
