--- Comment #2 from Nikolay Sivov bunglehead@gmail.com 2011-09-23 04:31:35 CDT --- I did yesterday, no change. The problem was also visible in product selection tree on Office 2010 installer - "+" expand button had black background just like icons in CSpy. Not sure Office example is still valid for current git, CSpy's is.
Could it be XRender problem on my side, bug or something? I use the one shipped with Debian 5, package manager says it's 0.9.4-2.
