Dear All,

 

Hello. I have a question about tearing issue with OpenGL + X11 in i.MX6DQ.

 

BSP : L3.14.28_1.0.0

Environment : OpenGL + X11

 

[Issue]

The tearing occurs when waiting for VSYNC and displaying.

  #define MXCFB_WAIT_FOR_VSYNC    _IOW('F', 0x20, u_int32_t)

  ioctl(fd_, MXCFB_WAIT_FOR_VSYNC, 0);

 

This Phenomenon looks below issue.

Refer to 6.1.7  Tearing in i.MX 6 Graphics User’s Guide, Rev. 0, 12/2015

There is description of "This tearing free feature will be described in next release.".

 

But, the below information seem to already fix this issue.

See Comment 4.

[Question]

When is this tearing issue fixed?

(Or, which BSP version was it fixed?)

 

Best regards,

Keita
