When setting a canvas object to use either masking or transparency, the object will no longer properly tile the texture when scaling. It will stretch out the texture.
Simply set a canvas item to either “Transparent” or “Masked” and try to scale the item.
Normally, the texture should be expected to have transparency, but still support proper tiling.
What happens instead, is that the dimensions of the texture will stretch out based on the scaling of the item.
The issue will persist if attempting to return to the “None” transparency mode; the item will need to be deleted in order to resolve this.
