** Description changed: + [IMPACT] + + On low-end systems, CPU is consumed by compiz, making the active blur + slower. + + [TESTCASE] + + No testcase except for no regressions. On most systems the impact is not + very noticeable since drawing of Dash items takes most of the time. + + [REGRESSION POTENTIAL] + + No known regression potential, tested on variety of drivers. + + --- + Compiz spends 94% of its CPU time in nux::GraphicsEngine::CreateTextureFromBackBuffer when the dash is open. unity::UnityScreen::paintDisplay() [98%] nux::GraphicsEngine::CreateTextureFromBackBuffer(int, int, int, int) [94%] nux::GpuDevice::CreateSystemCapableDeviceTexture(int, int, int, nux::BitmapFormat, char const*, int) nux::GpuDevice::CreateTexture(int, int, int, nux::BitmapFormat, char const*, int) nux::IOpenGLTexture2D::IOpenGLTexture2D(unsigned int, unsigned int, unsigned int, nux::BitmapFormat, bool, char const*, int) nux::IOpenGLSurface::InitializeLevel() ? _Mesa_TexImage2D
