[SOLVED] Kodi flickers when navigating

[grandcanyon]

Unfortunately, it still flickers only when navigating kodi. Not during playback. I have tried increasing the config_hdmi_boost but it doesn't seem to help. I though maybe it was because I had the kodi power plugged into a strip so I moved it to the wall outlet but this didn't help. I've tried to changing refresh rates but this didn't work either.
