Wow, that is an old regression.

I think it is somewhat strange that enabling the scissor test(which reduces the
area that is cleared) blacks out the screen. A more common situation is that
we're clearing too much, thus the screen gets black.

I can imagine two scenarios:

1) We're supposed to clear more than we're clearing, and the depth buffer
contains values that breaks further drawing

2) The scissor test doesn't get disabled properly.

I think (2) is unlikely. You can try that by adding a
glDisable(GL_SCISSOR_TEST) after the clearing is done.

(1) Can be tested by porting the clear tests from dlls/d3d9/tests/visual.c to
dlls/d3d8/tests/visual.c, and checking if the outcome is the same. Maybe d3d8
clears are not limited to the viewport like d3d9 clears are.
