XCB and OpenGL on Imx6 works in fullscreen mode?

Question asked by Alessio Lama on Sep 21, 2017

I'm using Yocto 2.1 system with X11 on imx6 platform. 

XCB/OpenGL apps have various glitches in fullscreen mode, GUI components have a bad refresh, I think caused by performance (e.g in normal mode an application use 25 % CPU, in fullscreen use 71% and some times is blocked).

I think that OpenGL accelerator is stopped in fullscreen mode but i can't be sure.

UPDATE:

es2gears_x11 FAIL in fullscreen

glxgears OK
