@arch linux 64 bit, kde 4.12 (the newest), oxygen-transparent from arch linux AUR (git version compiled or something close to it)

[EDIT]
it's bad subforum, i know. "New topic" has redirected me here by accident. Where this topic should be?

Can you please explain the issue in more detail? If the transparency is causing issues, please verify that the KWin window opacity is set appropriately - usually this is 100% though (ie. no transparency).

I've changed background opacity on yakuake to 40%, but it's default on dolphin. What information should I post? There are just afterimages and not properly working background transparency...

can you please post the output of

You might have to replace "qdbus" by "qdbus-qt4"

Although it doesn't look like so, try to disable the blur effect. If that "fixes" it, try to disable blur caching ("kcmshell4 kwincompositing", 2nd tab. caching is the only checkbox in the blur config dialog)

It doesn't fix anything.

Does the window "clear" when you eg. move it? Or trigger a repaint differently (eg. activating "present windows")?

It clears when I move it, but every repaint just draws on what was in before, making these afterimages.

please try

Code: Select all

export KWIN_USE_BUFFER_AGE=0
kwin --replace &


Just the same.

does this only happen with oxygen-transparent or also if you use a "solid" style and make the window translucent (Alt+mousewheel)?

It's oxygen-transparent only problem. I can add eg. yakuake and dolphin to oxygen-transparent exceptions, but then there is no transparency at all and it doesn't look well.

That's not entirely what i meant.
What if you add them to exceptions but still make them (globally) translucent?
(Alt+MW should do that, can be configured in the "Window Actions" tab of "kcmshell4 kwinoptions")
