Uncaught Excepton, Shader Error

[Ayu Sakata]

One of my players is unable to play [text]. She says she got this error when she tried to open the game:
I'm sorry, but an uncaught exception occurred.

Exception: Shader error: Fragment shader(s) linked, vertex shader(s) failed to link.

After initialization, but before game start.

It's unlikely to be game-specific. It's very likely to have something to do with her computer, drivers, etc.

Getting a copy of her opengl.txt file would be useful. After that, she can work around this by holding down shift, and selecting the software renderer.

Here's her opengl.txt:

I told her to hold down Shift when she runs the game, but she said that when she runs the game, the window flashes on the screen, then disappears.

This should be fixed in 6.12.
