open task manager and check eso isn't still running, noticed this myself when using alt+f4 to exit the game.

I already did that, but ESO is not in the Task Manager. The voices are the same before and after the game closure, but for example, now right click menus take a while to appear.

I been experiencing this problem too but luckily the slugging only lasts for about a minute or two at most. The issue seems to stem from when you play the game only and not when you just launch the client nor when you just sit on the character select screen. Only when you are playing in the game world then click on the "quit" option or just ALT+F4 will you occur this issue. I recently found out that when you instead click "log out" then select "back" on the character select screen then click "quit" on the login screen does the issue seem to not occur. I know this thread is a month old but I thought it was important enough to inform @MakTheEater on what I had found on my own. The reason why this is occurring, well I have no clue, I only know that this is a recent problem and not a late one.

TL:DR
If you want to avoid this problem just "log out" then click "back" on the character select screen then "quit" from the login menu. This issue seems to only occur when you "quit" from inside the game world only.
