It looks like that the #1230 (2017) is ok and #1231 (2017) not.
perhaps "New 4.14.10 kernel" or too much new years eve party ?

I downgraded from 1231 to 1230 (not my preferred method) and its ok again.

It's possible there's a conflict with the latest kernels.

I've rebuilt the lcdd addon and uploaded it: RPi2

Give it a try, if it doesn't work then please upload your kodi log from LibreELEC Settings > Upload log (as this will include dmesg information).  

Thanks for that.
But it didn't help.
I think i will follow the tip from Hias.
So the next step will be to contact the XBMC LCDproc addon author.
I won't switch back to the old Version. Amazon prime is back.
Thank you!
