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
