Kodi going black

Im using kodi on firestick tv and when i click on a link it then goes black but the sound is playing, but i cant exit the screen even when i press home on the remote its still black, but when i select source to change hdmi its dimmed. then when i go back onto the firestick hdmi i press home a few more times and its back on the app home page, the brightness is normal but when i click on kodi again it starts faded but then goes black again and i have no idea why its doing this and how to stop it. Just for reference my kodi is all up to date and checked my tv setting with micro dimming off? Please help
