In windowed mode, the rendering stays always on top, and moving a window causes a stale rendering to be left behind. In fullscreen mode, windows underneath cause a flickering effect. This is on R350/radeon hardware. ProblemType: Bug Architecture: i386 Date: Tue Mar 27 15:57:27 2007 DistroRelease: Ubuntu 7.04 Uname: Linux flash 2.6.20-13-generic #2 SMP Sun Mar 25 00:21:25 UTC 2007 i686 GNU/Linux ----- Issues with Composite and 3D are widely reported and show themselves in a variety of contexts, but all are derived from the same root problem. 3D apps wish to do direct rendering in order to maximize performance, but Compiz wishes to retain control over how all windows are painted and doesn't work well when apps are rendering directly. Thus, what's needed is a method to redirect these directly rendering apps. Redirected direct rendering is nicely described in this blog post: http://hoegsberg.blogspot.com/2007/08/redirected-direct-rendering.html The general effect is that when Compiz is active, running a 3D app like glxgears will show rendering errors when moving the glxgears window or putting it behind or over other windows. The standard workaround is to disable compiz while using the 3D programs and re- enable it when done. This is a general problem in X's core architecture, and not an issue particular to a given driver. It's not exactly Compiz's fault either, and unfortunately it lacks a mechanism to hide or work around the problem. Solving it requires modification of a number of components including adding the TTM memory manager to libdrm, modifications of DRI in X, and on and on. It represents a significant amount of work to be done upstream and will probably take on the order of a year or two to get everything sorted out.
