This is also can be included Evil-Spirit/solvespace@e07404a

The current master and opengl2 branches use the style like:

OpenGl1Renderer() : camera(), lighting(), current() {}

I cannot reproduce the bug on master or opengl2, when built with MSVC locally, or on Appveyor. Can you confirm that this problem is not present? Or show where the uninitialized data ends?

Note, camera{} is not the same as camera() so that's probably why I don't get the error...

@whitequark,
Yes, I still have this problem on master (GL Error 0x502).
This is because current.drawing not initialized with false

OK, I'll look further into it.

@Evil-Spirit May be similar to 86f0439.

@whitequark, yes this bugs of the same nature.

@whitequark also, commints from whole branch https://github.com/Evil-Spirit/solvespace-master/commits/93-not-initialized

@Evil-Spirit I finally figured it out, should be fixed in 43a59e2.
