Hello,

I'm suffering a new problem with Kde & Chrome. When loading some pages, a ghost image remains in somewhere, not visible in the root window but in in the applications one, over white backgrounds only. Maybe it happens with flash elements, but I haven't evidences enought to confirm.

Effect doesn't appear with ksnapshoot, so I include camera pictures

System is OpenSUSE 11.2; Dell Precision 6400 with Nvidia Quadro FX2700M (Nvidia drivers)

¿Any idea?

Can you please upload the pictures somewhere where I don't have to sign in?

only app affected is Chrome? all or only certain web sites?
what if you open chrome in Konsole with --disable-extensions

Same story here. Using opensuse 11.4 with firefox version 4.0b12. Appears to be flash coming through to the application window and the flash appears to be actually running so its not just and image coming through to the application window! Most annoying reading my email using kontact/kmail.

mrlinux this happened went you went to 11.4 and it came with FF 4.0b? were you running FF 4.0b previous to 11.4?

what version of Flash?

Only happens when FF is open and Flash is running?

Does it go away if you turn off composting?

The version of adobe flash is 10.2.152.27. Only started happening when upgrading to 11.4. Looks to be isolated to running flash. What is composting?

composting is the desktop effects like bluring, transparency, window animations and widow switching animations

systemsettings -> workspace appearance and behavior -> desktop effects -> uncheck "enable desktop effects"

does it happen when you run Flash in Konqueror or other browsers?

Turned off the desktop affects and using firefox with flash the problem hasn't resurfaced yet. Let me live for a day or two to see if the problem has been resolved.

If it's gone away you'll need to figure which effect is causing it, maybe change your desktop theme to one that is transparent (just a guess)

Hi -
I will not mark this solved until I can confirm this thing more, but people that have this problem, try to set VSync in System Settings -> Desktop effects -> Advanced tab -> Use VSync.

It seems that the problem is at least much better here (especially VirtualBox became usable, and it had a lot of ghosting effect). I have not seen ghost effects since then, but hey, it's just a test, so I cannot be sure.

I tried this because there was a thread with a similar problem in Unity with Intel cards, and was almost solved by some magic VSYNC env variable.

Hope this helps,
Romano

(Post script: ok, ghosts are not gone completely, sometime in VirtualBox I have ghost images that disappear with a focus/unfocus or a raise event. But it's on another order of magnitude...)
