Comment 8 for bug 1043443

I didn't have time to fix Greybird-compact before UI freeze unfortunately (my day also only has 24hrs), and this bug was noticed very late.

The problem is very specific, I got in touch with upstream Xfce developers because it does not occur only with shimmer-themes, but also with Xfwm4's default theme. The rendering-problem seems to be a combination of proprietary Nvidia drivers (or Vbox) and a newer version of Xorg used in Quantal. Also people from other distributions, notably Arch, have reported this.

There is a workaround to fix left* and right* sides of windows, but I will only apply (to shimmer-themes) it last minute, i.e. if it's clear that the problem can't be fixed in the real sense. Since also many other themes – apart from the ones installed by default – are affected (basically all themes that use pixmaps that are 1px wide or high), we can't "cover it up" completely with workarounds anyway...

@Paulo: Thanks for testing Quantal, noticing and reporting bugs – it's very useful for us!
