I am always getting told by users in secondlife that the one thing
they hate on other grids is the graphics and or textures.
The reason for this and this would likely be the reason you see the
starts as a shape is the way each graphics card displays graphics to
you. No to graphics cards actually display graphics pixels the same
way. In fact if you go into mouselook while set in Midday for your
sun setting and then look up at the sun youll see two rectangles. Ive
tried this on graphics cards from nvidea geforce, ATI radeon (my
current graphics card on my desktop) and Intel graphics (same as my
laptop's graphics card) and i get that. So its not really a bug or
anything its just the way its displayed via your graphics card.
Always be sure your graphics card drivers are up to date but not
really much you can do about that unless you feel like messing around
with the images in the scene code itself.
