Don't try DRI2/Present flipping while the HW cursor can't be used
Flipping doesn't interact correctly with SW cursor: A flip makes the SW
cursor disappear. It will only appear again when the cursor is moved,
but it will be surrounded by corruption, because the SW cursor code
will restore stale screen contents at the old cursor location before
drawing the cursor at the new location.
