glcompbench doesn't work on Efika MX Smart book

[Jammy Zhou]

glcompbench is a benchmark for testing the composite performance: https://launchpad.net/glcompbench

When run glcompbench on Efika MX SB, the window is always dark red, but there should be some texture images as expected. And it seems that the application enters endless loop when run with "--benchmark" option.

And if use X image instead of egl image for compositing test (use --no-accel-tfp option), segmentation fault happens for glcompbench when call glTexSubImage2D in CompositeWindowXImage::update_texture_from_pixmap.

The "--benchmark" option issue has been fixed in glcompbench. It turns out that the timestamp computation was never satisfying the time interval for computing FPS and updating the test iteration. The rest of this issue is still relevant.

I'm really not sure why it's segfaulting there..

Running the benchmark now I get a blue fadey window which shows we have absolutely terrible performance.

--no-accel-ftp still segfaults but I can't track exactly what is segfaulting or why. Does anyone have any decent gdb data from it? Is it crashing inside the app or the driver?
