There is no real fix for this but you are likely run Kodi at 4k res ? If so this is not really what you want. Kodi Ui is basically FHD only, using it at 4k just waste a lot resources. Btw even thats just the Kodi Ui, if you want to play a 4k movie it is still shown in 4k.
So just set the Kodi resolution to FHD and it should fix chrome too
