Roku slow to respond when navigating channel
I have a Roku3 and have been experiencing similar issues. Not only was the Roku itself laggy, but the lag affected apps differently. YouTube was by far the worst affected, lagging to the point of being unusable and often crashing to a gray screen that required rebooting the Roku before YouTube would ever work again.
I solved the problem (fingers crossed, knock wood!) by connecting the Roku to my router via Ethernet instead of wifi. Apparently, using wifi heavily taxes the Roku's CPU.
