Fabio: What I mean is:
1) I load Firefox. I set some web page with pictures below the visible area of
the page.
2) I have now the web page loaded.
3) I press down arrow or PgDn. Screen starts to flicker when the pictures below
start to appear. The flicker/tearing usually happens when scrolling with down
arrow (when the pictures start to appear). But with both down arrow and PgDn
the screen goes off ("no signal") when the picture(s) fully appear.
Then when the screen is in the "no signal" state I press up arrow or
PgUp. The same thing happens but in reverse, i.e: flickering starts when
part of the picture is shown and the flickering goes off when I scroll
to an area containing no pictures.
The same thing happens without Firefox. But in my test I use Firefox and
the scrolling because it's the easiest way to recover from the "no
signal" state. The Firefox setup is also easiest to reproduce because
other cases need windows in certain places of the screen and certain
content so it would be difficult to explain that setup in a bug report.
