I just upgraded my old laptop (Dell Vostro 1500) from
F24 to F25 using the "dnf" plugins.

Video is now a problem.  My selected desktop wallpaper
does not show, just a black background.  Once drawn on
the desktop, items remain.  For example menus still show
after making a selection although they are not active.
Moving windows leave lots of ghost trailing images.

If I switch workspaces then switch back the artifacts
are gone, but still no wallpaper.  The wallpaper does
appear for an instant if I logout or reboot.

My normal environment is sddm display manager, mate
desktop environment, and compiz as the window manager.
For the latter I've tried both the emerald and the
gtk window decorators.

I've tried display managers gdm and lightdm, window
managers marco and mutter, and desktop environments
cinnamon and gnome.  All exhibit the same behavior.

I also tried a root gui login to mate which exhibited
the same behavior.

The video hardware is nVidia GeForce 6800M, using Xorg,
not Wayland, and the nouveau video driver.  No xorg.conf
file in use.


Suggestions welcomed.
