R300 Graphics Improvements For KDE's KWin
If you're using any R300/400/500 GPU with the Gallium3D R300 driver, there's some improvements coming up for you in the KDE KWin compositing window manager.
Martin Gräßlin, the maintainer of KWin, has been aware of R300 rendering issues for a while but hasn't had access to any hardware that works with the "R300g" driver. Back during XDC2011 Chicago I passed along an ATI Radeon X1300PRO graphics card to get to him so he could work out these issues.
Martin now has the PCI-E graphics card and has already fixed up two texture bugs and has begun work on GL2 shaders for R300, which previously was completely broken. These are improvements lining up for KWin in KDE SC 4.8.
