"Even after updating to version 4.0.1 (4003), applying LT Global Background still results in the same issue shown in the image."

There seems to be an issue in that plugin that disturbed the drawing. Do you get any error in the Scripting window?

“Yes, an error occurs in the scripting window. The Python version is 3.14.6. I used it in Glyphs 3 without any issues. Are there any alternative options I could use instead?”


What error do you get?

The LT Global Background tool applies backgrounds inconsistently, functioning properly only on certain occasions. This intermittent issue is quite frustrating.
