Description Tomasz Dudzik 2009-04-09 20:38:44 UTC
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

It's so: when I right click on an icon in systray, like Akregator I get the menu. When I move the mouse on that menu, the shadow dissapears. It happens not only in systray. Check out the screencast I've done:

It's really annoying. Such bug can't stay in the most adcvenced desktop environment.
Comment 1 Martin Flöser 2009-04-09 21:40:51 UTC
The screencast does not load...
Comment 2 Thomas Lübking 2009-04-09 21:56:08 UTC
it's a html page, the cast resides inside an iframe

... ... ... D'OHHH!

i think this bug is strongly related to some cristoph posted earlier this day (or yesterday - but i forgot the bug id :-(

the bug alters when using translucent menus. in this case the menushadows are ok, but shadows from windows below get double painted and update on e.g. submenu mapping.

i can only confirm it for nvidia drivers, but the backend doesn't matter.
(the other bug is about complete window regions sometimes not getting updated after -afaics- fullscreen FX)

Right click, and save as should work. Is it possible to fix that Kwin's problem?

I'm experiencing the opposite: when the menu on the system tray is opened, the shadow appears only after some seconds and only if I've hovered a menu with a sub-menu: when the submenu is closed the shadows appears.

Git commit 3b8984d630cc6dc655a171fa9c0f7e74e9ee3c61 by Martin Gr����lin.
Pushed by graesslin into branch 'graesslin/kwin-cleanup'.

Remove Shadow Effect.

The shadow effect is known to be broken since at least 4.5.
It is unfortunately in a state which makes it difficult to maintain
and the architecture has some serious drawbacks. Therefore it is the
best solution to replace the effect with a new and better
implementation. For more information about the new implementation
please see the discussion on KWin mailinglist:
http://lists.kde.org/?l=kwin&m=129607406517609&w=2

This also "fixes" all existing bug reports about the shadow effect.
Most of the bugs will really be fixed when the new shadow system is
implemented, if not it is a new bug and a new report should be created
for it.

Please excuse that we go this unnormal approach to mark bugs as
fixed with code removal.
