Is TileMap unusable in editor on Mac? Godot CPU usage jumps to 50%, 1FPS

Godot Version

4.2

If TileMap node is selected in editor (2D view), Godot starts lagging like crazy. If I make the node invisible or select any other node, it goes back to normal.

It’s literally unusable when lagging, 1fps with every click delayed a few seconds. CPU usage spikes to 50%+.

Is there a workaround?

I’m on an otherwise-fast M1 MBP. Restarting Godot didn’t help. The game plays fine with tiles.

I think it’s literally drawing the orange grid shown when a TileMap node is selected in 2D view that tanks Godot. Doesn’t matter if parallax mirroring is on or off.

Try disabling the grid as a workaround.

And it would be great if you could open an issue here Issues · godotengine/godot · GitHub if you can’t find a similar issue already.

Ty sir, that fixes it. Will report the unexpected behavior.

This is an old issue with an existing tracker. The workaround specified there (using opengl13 renderer instead of opengl13_angle) doesn’t work for me b/c while it helps the editor to not lag, the game then crashes on launch.
