[light] object does not render in second [gemwin] unless sent [debug 1(

[rnkn]

Detail

My apologies if this is user error, but I can't figure out what's happening with this lighting.

I have found that the [light] object does not render in a second [gemwin] unless sent a [debug 1( message.

Here is my patch (also in plaintext at bottom):

Here's what I'm getting at step 1, 2, 3, & 4:

Enabling lighting only works in first [gemwin]:

Enabling debugging renders lighting in both windows:

Now lighting works as expected:

My assumption is that lighting in step 2 should work as it does in step 4. Is this my error, or a possible bug?

Thanks for your time.
