solid texture in N panel ?

what does this var " solid texture " does and when or not to use it ?

thanks

When you are in Solid display, and use a model that has a texture, enable the “Texture Solid” and it will show the texture on your model while you are still in Solid display.
The same as if you went to Texture Paint Mode.

solved this one
has to do with normals!

i saw something strange
i added something like a cube
and click on the solid texture and the upper and lower face vanished!

but is it samething then the bottom header
for viewport shading ?

and when you say texture you mean UV texture!

and ther is another one in object pane
draw type

it’s a lot of locations to play with solid and texture !

thanks
