[Bug 1037411] Re: [regression][GLES] Benchmark results are 15-40% lower with the gles2 code (compiz 0.9.8.0)
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?
