Hopefully this hasn’t been answered before or is covered in another forum, but this is my issue. I’m currently using KODI 16.1 with windows 7 and a AMD XFX RX-460P2SFG5 AMD Radeon 2GB GDDR5 DVI/HDMI/DisplayPort PCI-Express Video Card, connected through a DENON AVR S700W receiver. It seems no matter what resolution I have chosen I get mouse lag unless, I restart the receiver which immediately clears it up, this is temporary, if I leave it alone for a short period. I am currently using the most up-to-date drivers and windows 7 on that AMD 8 Core PC is pristine. The mouse lag only happens on KODI, FYI, which is awesome!
