Typically the issue also affects when you are browsing the web using Microsoft Edge, the tabs would stop responding or work. For some users, lock screen may perform abnormally slow.
If you are facing similar issues after updating to 1809 then you are not alone, Microsoft has isolated this issue and only affects to those users having AMD Radeon HD2000 or HD4000 series graphics card.
As per Microsoft, this issue affects following platform users,

The AMD no longer supports these graphics cards so there is less chance of getting driver updates and Microsoft is already investigating the issue to find the root cause.
In meantime, Microsoft has blocked Windows 10 October 1809 update, that also means if you are using HD2000 or HD4000 graphics card, then you won’t get 1809 update even after hitting Check Update Now manually.
Although, there is a way to get 1809 update via Media Creation Tool.
