Bug 166868

Version:            (using KDE 4.0.98)
Installed from:    Unlisted Binary Package
Compiler:          gcc 4.1.2 
OS:                Linux

I'm using KVM on Linux 2.6.25.10 x86_64 both for the host and the guest.  I've tried both -std-vga and without for kvm's options.

When I log into KDE 4.1rc1, plasma starts, but only fills 3/4ths of the horizontal space on the display.  It's like every 4th pixel gets dropped (which causes a kind of pin-striping effect).  Then, when kde starts to launch my session applications, X crashes, and I get kicked back to kdm.

I've isolated this by running a failsafe login, then launching plasma manually (same squished screen).  Plasma starts up, and I can use the menu, etc. (Though it looks like all the widgets have the same squished effect).  Then, if I launch klipper or korgac or something that tries to draw to the applet area, X crashes, and I'm back to kdm.  Interestingly, the failsafe window doesn't get squished, and kwin's window borders appear normal.

I will attach a screenshot that illustrates the pin-striping.
