Hello,
I met the same kind of error recently. The "bit per pixel"
of the framebuffer interface should be 32, you can check/change the
value in /sys/class/graphic/fb[x]/bits_per_pixel. Default bpp can be
specified in DTS.
I also remember that IPU configure DMA with burst
size and each line will must be a multiple of this burst size. This may
be related with your error for line width = 1366.
Regards,
Vincent

eglfs running on that resolution?
