Seems to come from:

It was not possible to use CanvasTexture in TileSets before at all, so it's not really this change that caused the issue. So it's not a regression either.

@Az-qianchen have you tried disabling "Use texture padding" ? Do you see any difference ?

My bad, the issue title made it sound like it made it a CanvasTexture causing bugs, instead of that it happens when someone assigned one, updated the title

After the change, I got the right result
