Description of problem:
I upgrade RH7.2 to 7.3. Now, since the begining of the session, at login screen,
mouse pointer shows two rows at the bottom of the sprite that disapears when the
mouse is redraw by pointing it over some text. Then, in Gnome or KDE, noise
pixels appear again and again specialy when dragging window`s bars, when opening
menus or pushing buttons. Again, pointing it to something that makes the pointer
redraw, i.e. a text, makes noise pixels disappear, just to appear again on the
next fast move or while opening a window menu
With RH 7.2 this never happened

Maybe related: In some circumstances, screensavers can't hide the screen and
start to draw jus over the desk image, like if the saver's background was
transparent.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Noise pixels appears from the begining in the login screen. Noise disappears
moving the mouse over a text
2. Dragging a window bar at normal or fast speed cause noise to appear. Dragging
slowly do not generate noise pixels.
3. Opening certain window menus

Screensavers:
1. Start a KDE session and select Matrix screensaver
2. Go to a console screen and work there enough time to let screensaver trigger
in the graphic console
3. Go back to graphic console
	

Actual Results:  Two rows of random pixel noise appears at the bottom of the
pointer sprite

Screensaver:
You can see a serious damaged image of the desktop and the screensaver drawing
over it, like if the screensaver background was transparent.

Expected Results:  Pointer sprite should be clean

Screensaver:
Bacground should be black and desktop image should be hidden
