Had a look at your code, looks like you need to turn on depthWrite on the taskbar material.
You can intercept it in the material.traverse on line 70. Just chuck in something like “if material.name == ‘Working_MoniterScreen_Taskbar’” and then override material.material.depthWrite to true.
p.s. I’d suggest renaming the variable “material” to “mesh” or “object” to better represent what it is.
