If I start any application which requires a depth buffer and runs itself in single-buffer mode
horizontal stripes are visible. The depth buffer is only partially deleted. This results in
the stripes.

The bug can be reproduced very easily. I have the MesaCVS sources. In the samples
directory, there is a prog called "depth". If you run "depth -db" all looks right. But if
it is run as "depth -sb" then the error gets visible.

    I\'m actually seeing different, but also equally wrong behavior. We do need to look into this.

    I can\'t reproduce this in my latest build. Can you check it again. We
    had some trouble with incorrect screen coordinates during one of the
    recent patches.

    Please try the latest code and let me know if it stil fails for you.

    I still can\'t reproduce this no matter what I do.
    What card are you using and at what resoution? I\'m thinking maybe the memory layout bug put the depth buffer past the end of the memory on your board.

    We\'re going to close this for now, and open it again if the problem persists after the next release.
