Bug detailed description:
The desktop is gnome. With compiz enabled, the cursor format and cursor blink rate in console is wrong. For example, typing a character in console gets 2 extra black blocks(can be seen on the screenshot), or the cursor is always blink. It works fine if disabled compiz. This issue happens after the Bug 25409 was fixed. Following is the bug report:

Reproduce steps:
1.start gnome
2.open a terminal
3.typing any character

    batch: Ensure we send a MI_FLUSH in the block handler for TFP
    This should restore the previous level of synchronisation between
    textures and pixmaps, but *does not* guarantee that a texture will be
    flushed before use. tfp should be fixed so that the ddx can submit the
    batch if required to flush the pixmap.
    A side-effect of this patch is to rename intel_batch_flush() to
    intel_batch_submit() to reduce the confusion of executing a batch buffer
    with that of emitting a MI_FLUSH.
    Should fix the remaining rendering corruption involving tfp [inc compiz]:

It works well. I verify it.
