No :-( I have tried the patch mentioned in the original thread and it didn't solve the issue. For the moment, I have given up and I'm working full screen. I will debug perhaps later if I have time. If anybody has any idea, it's more than welcome to share,
Grégoire PS: Also, there is another bigger (for me) problem: OMAP3 + PowerVR graphics libraries + "cogl_enable_depth_test(TRUE);" doesn't work. I get some driver errors and the stage output shows random noise :-( I will write an extended report later. I have not yet figured out if it's the driver or if it's inside the eglx backend. Any idea on this issue is very welcome too.
