Hello,
I've upgraded my HTPC to 7.90.010 from an Openelec setup and I get very serious ghosting and blurring of the symbols when I navigate around the UI.
Watching files is better, but with an occasional distorted line appearing near the top of the screen.
I'm running a Zotac Nano AD10 box, which is an AMD E-350 processor with AMD Radeon HD 6310 graphics.
I've run a similar setup with a RPi3 and had no problems whatsoever.
Many thanks
