Description

Created attachment 63374 test app

After upgrading OLPC XO-1 from Fedora 14 (xorg-server-1.9) to Fedora 17 (xorg-server-1.12) we are seeing problems with GNOME's notification area. The icons appear all-black, which is the same colour as the GNOME panel which they are drawn upon.

I've narrowed this down to a simple test case (attached). This program draws an icon (works OK), then when the window is resized the icon is replaced with all-black.

Initial diagnosis at http://dev.laptop.org/ticket/11860 suggests that we're receiving a composite PictOpSrc request with no mask, repeats or transformations. lx_do_composite then reacts in this way:

    /* All black out of the source */
    if (!exaScratch.repeat && (exaScratch.type == COMP_TYPE_ONEPASS)) {
	    lx_composite_all_black(srcOffset, exaScratch.srcWidth,
		exaScratch.srcHeight);
    }

and the icon goes black.

We are not 100% sure if this is a Geode bug or something wrong in the X server. A good first step would be to understand how the driver should respond to PictOpSrc with no mask, repeats or transformations, and if that is even valid at all.
