Version: (using Devel) Installed from: Compiled sources OS: Linux Drop shadows behind widgets (e.g. menus and drop-down lists) partially disappear and don't redraw. This happens when selecting a menu item with mouse pointer, or when scrolling through menus in succession. I have a nvidia 7300LE video card with nvidia proprietary drivers ver. 173.08.
Have you experienced this bug again with a recent KDE version? (4.1.3 / 4.2beta2 / 4.2svn) and updated nvidia drivers ? Thanks :)
I have KDE 4.2 und NVidia driver version 180.29, and I still see this.
Updated to KDE 4.2.2 and NVidia driver 180.44, and I still see this.
Interestingly this problem does not appear, if I enable the 'blur' plugin. However, the blur plugin causes new problems (namely, graphical corruption and the plasma panel jumping up and down by one pixel when switching desktops), so I have to keep it switched off.

I have a gentoo box with a Nvidia GeForce 7600 GT and 180.44 drivers and KDE 4.2.1. There I can see this bug However on my Kubuntu laptop with Nvidia GeForce 9600 M and 180.44 drivers and KDE 4.2.2 everything is fine.
Upgraded to KDE 4.3 beta 1 (on my kubuntu laptop). Now I have the same problems and some new ones: - shadows are not redrawn - the corners of menus sometimes get black edges - a submenu which should overlap the root menu is transparent and I can see both. I guess there is either something messed up with the z-values (is depth test enabled? Does every menu have a reasonable z-value?) or something is messed up with the alpha values (is the proper alpha function used? are menus drawn from back to front (or front to back respectively depending on the alpha function used))

There is a known bug in beta 1 concerning decorations which has been resolved. So very likely that problem is fixed as well. If not it could still be another issue for bug #193808. > > I guess there is either something messed up with the z-values > (is depth test enabled? Does every menu have a reasonable z-value?) There is no depth test
I have made a new observation: Disabling the translucency plugin fixes the issue. The shadows are also drawn correctly when the translucency plugin is enabled, and the menu translucency is set to less than 100%.
can you still confirm this with some 4.3rc or trunk?
I installed 4.3 just now. It's working!
