ioQuake latest test shadow-bug in opengl2

Hi all!

Just found this oddity:
When switching to opengl2 the weapons that would cast a shadow on the ground in opengl1, now have a huge rotating square under it.

opengl1:
[sigh - new users only allowed to show 1 image… see reply below]
opengl2:

And it doesn’t apply to just weapon-shadows, also using the railgun has a similar effect.

without rail in opengl2
[sigh - new users only allowed to show 1 image… see reply below]

I’m playing with cg_shadow 1 or 3 which solves the square-issue (default = 2), but doesn’t give the cool projected shadows.

Is it just me? Did I goof something up?
