Description Jure Repinc 2011-05-15 03:57:47 UTC

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

I compiled latest mesa (git-51d0892) on my other, desktop computer with ATI Technologies Inc RV350 AR [Radeon 9600] and it has the same problem. Xorg server is 1.10.2, Linux kernel is 2.6.38.4 and KDE us also 4.6.3
