F13: KDE crashes with OpenGL effects turned on, Intel graphics

[Thomas Ritter]

Hi,

I'm using Fedora 13 Alpha/Beta on my ThinkPad T410s with Intel graphics.

$ lspci -nn|grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor 
Integrated Graphics Controller [8086:0046] (rev 02)

$ uname -r
2.6.33.1-19.fc13.x86_64

When I turn on OpenGL graphic effects, KDE crashes if I open a new application. 
It does not happen when I turn on the XRender option instead of OpenGL.
When KDE crashes it returns me to the kdm/login screen.

Where can I find more information on this bug (logs...) and is this bug already 
known? I did not find anything on bugzilla.redhat.com on this.

KDE does work pretty well with effects turned off by the way (and does so 
reasonably well with XRender effects)
