Hello. I have a question about tearing issue with OpenGL + X11 in i.MX6DQ.
BSP : L3.14.28_1.0.0
Environment : OpenGL + X11
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.
When is this tearing issue fixed?
(Or, which BSP version was it fixed?)
