Line probe glyph coloring/hiding
In line probe module when "index" slicing is chosen there are some issues with the glyph.
test field -> line probe - why the glyph is colored with such a strange rainbow colormap?
click 'add current probe' and move the glyph - glyph coloring changes, why?:
click 'hide glyph' - sometimes (when? why?) all probes disappear and a longer refresh is running or sometimes nothing happens and the glyph is not hiding
