Something like the following always fixes 99% of the corruption issues i'm
seeing with radeon:
--- a/src/radeon_exa_funcs.c
+++ b/src/radeon_exa_funcs.c
@@ -401,7 +401,7 @@ FUNC_NAME(RADEONDownloadFromScreen)(PixmapPtr pSrc, int x,
int y, int w, int h,

-    if (info->accelDFS && bpp != 24 && RADEONGetDatatypeBpp(bpp, &datatype) &&
+    if (info->accelDFS && bpp != 24 && w>32 && RADEONGetDatatypeBpp(bpp,

        (scratch = RADEONCPGetBuffer(pScrn)))
     {


I guess it is obvious why; For small pixmaps things are already used before
they are completely there.
