Short description of error
Light 'normal' texture coordinates in nodes for spotlight not working anymore like it does in blender 3.00 as expected.
You have to switch to reflection in texture coordinates of the light nodes to get a projection from the light.
(Not sure but was it always possible to archive this with the other lights too?)

Exact steps for others to reproduce the error
Open attached file in blender 3.0.0 stable and switch to rendered viewport. (you'll see window shades shadows).

Then open the same blend file in any blender version 3.1, and you see that it's not working anymore, unless you switch the texture coordinates of the light to Reflection.
(And then you can't change the lights z rotation under item-panel to change angle/direction of the shades light projection. )

But the main problem is the texture coordinates for the lights aren't working as in blender 3.0.0 stable anymore

Thanks in advance
