Found a memory leak in GraphicsSurfacePrivate::findFBConfigWithAlpha(). ==21489== 14,720 bytes in 23 blocks are definitely lost in loss record 3,184 of 3,192 ==21489== at 0x4C2B6CD: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==21489== by 0xCB26915: XGetVisualInfo (in /usr/lib/x86_64-linux-gnu/libX11.so.6.3.0) ==21489== by 0xC8A72CE: glXGetVisualFromFBConfig (in /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2) ==21489== by 0x9EF97F5: WebCore::GraphicsSurfacePrivate::findFBConfigWithAlpha(__GLXFBConfigRec**, int) (GraphicsSurfaceGLX.cpp:355) ==21489== by 0x9EF931E: WebCore::GraphicsSurfacePrivate::createPixmap(unsigned int) (GraphicsSurfaceGLX.cpp:249) ==21489== by 0x9EF970F: WebCore::GraphicsSurfacePrivate::glxPixmap() const (GraphicsSurfaceGLX.cpp:336) ==21489== by 0x9EF8382: WebCore::GraphicsSurface::platformGetTextureID() (GraphicsSurfaceGLX.cpp:419) ==21489== by 0x9EF85D0: WebCore::GraphicsSurface::platformSwapBuffers() (GraphicsSurfaceGLX.cpp:454) ==21489== by 0x9EF799B: WebCore::GraphicsSurface::swapBuffers() (GraphicsSurface.cpp:78) ==21489== by 0x9471B07: WebCore::TextureMapperSurfaceBackingStore::swapBuffersIfNeeded(unsigned int) (TextureMapperBackingStore.cpp:45) ==21489== by 0x56AC2C8: WebKit::LayerTreeRenderer::syncCanvas(unsigned int, unsigned int) (LayerTreeRenderer.cpp:252) We should free the XVisualInfo returned by glXGetVisualFromFBConfig() to avoid this leak.
