Your hack is cool but what took my attention is the fact I'm getting almost the same YouTube suggestions you are getting, which to me proves how broken that feature is...
I feel the mi box is just too zoomed in at 1080p.. tried adjusting the pixel density.. default was at 320(top picture) 2nd picture is at 250(below)
i'm getting more icons and images fit in @250..
How did you change it?
You're playing with fire.....
I noticed that doing the wm density to any values breaks the alignment of the leanback keyboard.
the other option is to use "wm size 2560x1440" or to any 16x9 resolution. keyboard alignment remains intact.
