           Summary: RS482: Screen starts flashing after screensaver with
                    KDE KWin desktop effects enabled
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: jlp.bugs@gmail.com


After a very long time I have got my old laptop with integrated ATI Radeon
Xpress 200M. I remeber running it with desktop effects enabled and classic mesa
r300 driver just fine. Well now wit Gallium I have this annoying problem:

I have the screensaver set to Solar Winds from KDE's kdeartwork/screensaver
package. As usually I left the computer alone and when I came back and moved
the mouse screensaver turned off. But what started happening was that the
screen was flashing. Parts of it (rectangular) were becoming black or werw
coming from black to normal. Thoose parts are the parts that the mouse was
traveling over. Just as if the damaged areas which needed redrawing.

To make this go away I had to turn off the desktop effects (using
Alt+Shift+F12) and then turn them back on (with same keybiard shortcut).

The flashing effect is especially visible if I have the KDE's Screen Saver
control center module open and test OpenGL screensavers from there.

Reproducable: always

Software in use:
* mesa: git-bd5b7a6
* kde: 4.6.3
* xorg server: 1.10.1.901
* linux kernel: 2.6.39-rc7
