Describe the bug A clear and concise description of what the bug is.

Any effect I try to use on the entire display will not work. It crashes xlights and has also crashed the computer. If I attempt to use a single line instead of having a line the display will flash. If I attempt to use snowflakes nothing happens on the house preview but on the model preview a little dot appears at the top and bottom but nothing on the house
