Created attachment 53261 [details] screenshot chat window I am using the statically linked skype-2.2.0.35 binary, selecting text in the chat window characters results in garbled text rendering. Also menu-entries which are renered selected result in garbled text. I wasn't able to reproduce the issue with QT4 applications shipped, the version I see the issue is available here: http://www.skype.com/intl/de/get-skype/on-your-computer/linux/downloading.static intel i945GM intel-git libdrm-2.4.27 pixman-0.23.8 linux-3.1.0 xorg 1.11.1

Having just found a very, very similar bug, I think this is going to be fixed by: commit 8e775cecccebe543d344721d45b2d43ee9f122b3 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Nov 7 20:01:33 2011 +0000 sna/gen3: Fix false reduction of ComponentAlpha with white source The principle behind the opertator reduction of WHITE * maskca is valid, except that we failed to account for the src/mask transposition when emitting the vertices - garbage ensued. Given that we agressively reduce the shader required for WHITE * maskca, it does not seem worthwhile to special case the primitive emitter as well.
