Bug Description

Description: Ubuntu maverick (development branch)
Release: 10.10

Just upgraded Kubuntu to Maverick RC & can't seem to get transparent plasma panel. Also the window decorations and menus are not transparent any more.
What seems quite strange is that when I click the panel's cashew the drop down menu is transparent for a second before it also looses transparency.

Under Lucid with KDE SC 4.5.1, I just had transparent panel, menu, window decoration.

My graphics card according to lspci:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

same here with Maverick RC: I upgraded to maverick yesterday. The bug does not appear when i'm using kubuntus livecd. Also transparence was working yesterday, so I guess an upgrade is to blame for it

y graphics card according to lspci:
02:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850]

I tried with the open source driver and fglrx: transparent plasma panel + decorations are not working with either of them

affects: ubuntu → kdebase (Ubuntu)

Same here. Never ran lucid. But I did not experience this bug the first boot directly after a clean install from the Maverick Kubuntu DVD. I have a laptop with switchable graphics (Intel + ATI), but I quickly disabled the discrete card and blacklisted the driver. I also upgraded to KDE 4.5.4 from kubuntu-ppa. The next boot, I had this bug! Hmm.. I also added an option "acpi_osi=Linux" to grub, but that was later, should be unrelated.

I've tried the following (in this order):
1) Delete ~/.kde directory and log in again.
2) Downgrading to non-ppa KDE.
3) Trying out Gnome which did not show any sort of rendering bugs.
4) Upgrading intel driver (ppa:ubuntu-x-swat/x-updates and ppa:xorg-edgers/ppa)
5) Upgrading to KDE 4.6 Beta 2 via kubuntu beta ppa.

I did not try to enabled the discrete adapter.

Kwin settings:
OpenGL (and all defaults) = This bug
OpenGL w/o blur effect = The kickoff menu, notifications and bar are transparent! but way too transparent. Text in notifications become very hard to read.
The setting "Transparency" does only affect window transparency, which works fine anyway.
XRender = Seems to work fine.
