After extensive testing I have determined that my initial conclusions hold.
With all else being equal (this took some effort), if the python environment leois running under is native to the OS the stylesheet is flawless. If leo is running under a venv of any flavor (including conda) the artifacts appear. Changing the stylesheet while using the venv doesn't work. Gammaray doesn't help. As far as it is concerned it is the same object with the same properties. I am stumped. Chris -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
