Created attachment 3612 artifacts during top Since upgrading from xfce 4.6 to 4.8, I'm seeing strange artifacts while using various applications. Most often, I see them in Terminal, but I've also seen them in firefox. In Terminal it's just text, but I tend to see the oddness in firefox with images, much less often with text. When it happens, selecting things in the affected application makes them go away. Scrolling in Terminal will invoke the problem even after "selecting it away." Sadly, I do not have concrete steps to reproduce. I tried disabling compositing, but this had no effect (though I didn't try restarting X when flipping back and forth between compositing). I was able to capture the effect with screenshots, so I'm guessing that it's not a direct rendering / video card problem; but, lspci says I have "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)". I'm using the i915 driver.

That seems to be a bug in your Xorg driver, nothing to do with xfwm4.
even less with the gtk2 engine :)
Yeah, I really wasn't sure what product to select, so I figured that the widget rendering engine would be the best guess. It looks like I upgraded xf86-video-intel from 2.9.1 to 2.14.0 at the same time as the xfce upgrade. I upgraded kernels from 2.6.36 to 2.6.38 several weeks later, but I'm pretty sure that had no effect on this situation. I'll try downgrading to xf86-video-intel-2.9.1 and see how that works out. Thanks for pointing my barking to (hopefully) the right tree.
