I run the game on PC. I play in the NA realm. My current ESO is "patch 5.3.8", running on Windows 10 Pro x64/1909 (18363.752) (I check for and install OS patches regularly, several times a week). Several NVidia drivers have been in use recently, culminating in v445.75 for WIndows 10 x64, GeForce RTX 2080 Ti (I check for and install graphics drivers regularly, several times a month). This is a recently integrated system, a matter of 6 months old. Having said all of this, I play several games, none of which have any problems (i.e. this appears to be unique to ESO).
During normal game play, when I am engaged in an "idle" activity (interacting with an in-game merchant/banker/crafting station, looking at my character's inventory, or simply standing idle doing nothing), the game will switch to a load screen, without warning. It does this often, both in isolated instances, as well as repeatedly every 1-3 seconds, many times in a row. The load screen is visible for a very brief interval (less than 1 second for each instance). It does this on latency numbers under "100".
I believe this started with "Update 25", but I am not certain exactly when. It has become a severe/chronic problem this week (after one of the small updates in the past few days).
Historically, this also happens while I am moving through the game world, but in a much more isolated fashion, a single short-duration flash to a loading screen (i.e. without a repeat of the incident), perhaps once or twice an hour as I play. This less severe manifestation has been occurring for a very long period of time (since Elsweyr, at least, possibly before). It looks exactly the same, from the user's perspective.
So far, this has not happened during PvE "activity" (gathering, fighting with NPCs, etc).
This is a problem seemingly different from the problem when the 3D world disappears when the player character reaches certain locations in the game world (which has been documented elsewhere, was easy to reproduce, and in any event did not happen when engaged in an "idle" activity).
Every time this happens, it tosses me out of whatever I am doing (interacting with merchant, banker, crafting station, looking at character inventory, or moving through the game world, in which case I stop in place), which requires me to re-start the activity (including fresh keyboard input to re-initiate movement). In the past few days, this has become EXTREMELY disruptive, especially when it happens in rapid succession (often, I have only enough time to re-initiate interaction with the merchant/banker/crafting station, or open my inventory, before it happens again and tosses me out; of course, if it happens when I am standing idle, it is much less disruptive, there is no interaction to be interrupted). At its worst, in renders the game unplayable.
Connectivity between client and server is not interrupted, this manifests purely as a user interface glitch. There seem to be no relationship with how I connect to the game (directly/via VPN, wired/wireless, etc), and seems to bear no relationship with the quality of my network connection (latency, regardless of whether it is mild or severe, does not appear to induce this problem). The client is not disconnected, it just interrupts whatever I am doing in-game (including doing "nothing", no keyboard/mouse input at all), wherever I am doing it, with a loading screen, without warning and without apparent cause.
Hopefully others are experiencing this as well, and can supply additional information. Hopefully you can find a way to reproduce this and isolate the cause. Its bad news.
Update: this can also interrupt the logout process... serially for sustained periods of time. This necessitates closing the game client window, or killing the game client with the Windows task manager.
