Description of problem:
Using KDE, when switching between virtual desktops the background wallpaper is
not refreshed. The correct background can be revealed by switching to another
virtual terminal and then switching back, or by "wiping" the screen with any
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Assign different wallpapers to different virtual desktops.
2. Switch between virtual desktops, the background will not change.
3. Switch to another virtual terminal and back to reveal the correct background.
Video card is Matrox Millenium G200 AGP.
You have to disable "common Background" in this menu. after that it should work
I had to disable "common background" before I could even set different backgrounds
for different virtual desktops. Please note the fact that I can cause the correct
background to display by switching to a different virtual terminal and back,
forcing the background to be redrawn.
This bug only appears when "Enable Icons on Desktop" is unselected in the KDE
strange, it works for me even i have unselected "enable Icons on Desktop" and
"Common background". I really cannot reproduce it on many local machine here.
Sorry, i close it as wontfix again
