I am using imx6 to display some graphs with OpenGL(config as FB). I found some strange phenomenons(oblique screen tearing) apear like this.
tearing picture right picture
It does't looks like screen tearing appearing when write the device "/dev/fb0". Did anyone know how to fix this problem?
I used "eglSwapBuffers(egldisplay, eglsurface);" to flush the buffer. And the code is modified by the gpu_sdk_v1.00/Samples/GLES1.1/01_SimpleTriangle.c. I just modified the left and right vertex position, the top vertex is changing with frame number.
Doesn't anybody meet this problem?
