In my experiments on SabreLite board I am using the following components of graphics stack:
- libGL/libGLES/libGAL/libEGL binary libraries from L3.0.35_1.1.0 rootfs image
- X11 driver vivante_drv.so built from sources (EXA part of xserver-xorg-video-imx-viv sources)
- X11 DRI library libdri.so built from sources (DRI part of xserver-xorg-video-imx-viv sources)
- xserver 1.11.2
- twm window manager
3D rendering with simple X11+EGL+OpenGLES2.0 examples to fullscreen x11 window works fine. However I see blank windows for any windows size other than full screen. I am wondering if current release supports DRI rendering only to full-screen x11 windows ?
