Just curious, @Vimmelthevampire you're using Kodi on CoreELEC or LibreElec, aren't you?

Are you experiencing the same issues I mentioned in #2293 and #2302?

Under AlexElec and viewed on a 100 inch projected screen, I don't see the issue you describe.
I see the original boxset image behind the cases when the individual movies extract themselves.
I will test tomorrow on libreelec/ raspberry pi.

My bad. I was in mq8. In mq7, initially the posters were too big for the frame surround. This however was rectified by cycling the center focus button. It now looks good in center list kodiflix.
Edit. The problem seems to afflict only mq7 and not mq8. Cycling center focus kicks me out of slide cases, the problem reappears when I select cases again.
The poster thumb overlaps the frame surround at the bottom and to the left.
As it works fine in mq8 I would guess its not a platform ( Alex/LibreElec) problem.
Hope this helps.
