No, you're just the first lucky user trying X 1.19 on i.MX6Q.

Fortunately for us Yocto users already faced that actually:
https://lists.yoctoproject.org/pipermail/meta-freescale/2017-January/020127.html

It seems that this patch is required on xserver:
https://patchwork.openembedded.org/patch/136696/

Can you try it and let us know how it goes?

Thanks,
Gary
