Script icons disappear

[Davider]

Several tree/list controls in the LA window display icons. When icons disappear, in which control? In all?

I haven't paid attention yet, In all panel , Open, Tasks, Files (NOTE: The icons in the top menu bar are displaying correctly)
 

When icons disappear, try to resize the panel (drag the splitter). Do icons reappear then?

NO

I've tried various methods, such as clearing the desktop icon cache and reinstalling LA, but the icons still aren't displaying
No icons. Now I don't know which one is the class file 
 

resize the panel (drag the splitter)

only solve the black box issue

I just discovered that some icons can be displayed when creating new files.
