vivante 5.0.11.p4.5 problems

I'm seeking some help with unofficial kernel I'm trying to use (3.14.54 from solidrun and 4.4 from xbian) with openelec. Few months back I had everything running but now I have video on hdmi and 7" LVDS 800x480 but 15" LVDS 1366x768 doesn't work. Kodi is saying the text below. Splash is visible in all 3 cases.
I would be very glad if someone could help me with this.
Thanks in advance for any tip to get this running.

Code:

I noticed that if I change resolution to 1368x768 kodi starts. Wondering why...

Hi vpeter,
I've shared your help request on UDOO's Facebook page.

 

I think I fixed already. The problem is that IPU needs X and Y by modulo 8 and driver in my kernel doesn't fix that. 1366 is not by module 8. Only 1360 or 1368.
Seems I'm on track to use new kernel for my imx6 devices. One nice feature with 4.4 kernel is docker support.

 

Hi, Do you know where is a problem, I have that same on 5.0.11p7.3

 

Not sure if correct solution but I changed in dts resolution from 1366x768 to 1360x768. So both are divided by modulo 8. And IPU seems to be happy
Now there is small black vertical bar few pixels width at the right part of the screen.
