I already did it some time ago, with no result. I did it again now, but cat /proc/cmdline report the same result as before:

This happen for example on a mouse right button menu, or when a hyperlink description appears on the screen bottom when mouse pointer cross some field on a webpage, also when favorites menu appear. The flickering usually disappear in a few moments, sometimes (usually when a few pixels are updating) it can last for seconds.
