I'm a little confused by that. Changing from tmpRegion to screen->region () effectively meant that the entire backing framebuffer object is painted to the backbuffer, rather than a small portion of it. This is necessary because we are always using glXSwapBuffers and the backbuffer becomes invalidated upon swap.
Why would this change have anything to do with the slowdown if the slowdown still occurrs when painting from a framebuffer object is turned off as you put in the description? -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1037411 Title: [regression][GLES] Benchmark results are 15-40% lower with the gles2 code (compiz 0.9.8.0) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1037411/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
