The test sends a PresentPixmap request with a notify entry from a
byte-swapped client. Without the fix, the window ID in the notify
is not swapped, causing dixLookupWindow to fail with BadWindow.
With the fix, the window ID is correctly interpreted.
See 925edb6c9e ("present: Fix missing byte swaps in sproc_present_pixmap()")
