my home page has 3 vertical stacks, they each have a few horizontal items to create a nice view that fills my wall mounted tablet screen. its been working like this for ages.
since upgrading to 8.0, the 3 vertical stacks show up initally, but after a refresh the 3rd stack drops below the first 2 and its now off the bottom of the tablet screen…
is there something i need to change ?
stack width or some page margins / borders ?
I see the same behavior. So, I will join the row waiting for any kind of help 
Do you have a screenshot of how it looks now?
I always thought that only the Core update changed how the cards and front-end worked (like 2022.5 release) and not the HA OS release like 8.0. That was always the under the hood OS was my assumption.
It is, this very likely has nothing to do with the OS change from 7.6 and 8.0.
I have this, running HA supervised on a dedicated Intel machine.
On the tablet, running Fully kiosk browser app - with HA companion as the only allowed, auto starting app. (So, NO BROWSER used, it’s the HA app, you see.)
I have three vertical stacks. But since a month or two mostly only 2 are next to each other, sometimes even only one. Rarely I see all three.
This is a daily problem. But by not having the time to figure out right now, I just did leave it for later.
Strangely, last week I did see this behavior also on Firefox in Windows, but that only happened twice or so. Far not as often, as on the tablet.
Just curious if you’ve tried viewing your dashboard in the Fully Kiosk browser (and not the HA Companion app)? Is there a reason you need to use HA Companion on the tablet? I run Fully Kiosk Browser on a Fire10 with just the built in browser and it works fine. I’ve never seen the issue you demonstrate here. At the very least it might be able help you narrow down the problem to HA Companion (or not).
I would try that on friday, no time to tinker now…
The reason to choose the app was then, that the app was already running anyway (for the available sensors), so just to save some memory.
And, exactly, as I wrote the last message, I’ve opened the browser on my Windows machine and guess, what I see?
So, no, it is not the app only…
And after a refresh op the page all is back to normal again:
Since a month or two? There have been two new Core updates in the meantime. Also what Core version were you running before?
Your pictures lead me to believe you might be using Layout-card, which allowed you to create that view. Layout-card has been updated a few times for the last few months. So for all we know, you were running a Core version from months ago and Layout-card from months ago as well and after updating everything, your codes don’t work anymore since Layout-card updates have had breaking changes.
If you’re not using Layout-card, then it’s rather difficult to figure this all out only with pictures and no knowledge how your dashboard is setup and what Core (and card) versions you were running before and are running now.
One thing is for certain: it has nothing to do with HA OS 8.0 (that has no effect on Dashboard/cards and wasn’t even released a month or two ago when you problems started.)
Assumptions are not needed and will lead to misjudging…
No, I do not use Layout card.
I did update everything I do use on the days, the updates are published.
All you see in my snapshots are standard elements from HA.
Three vertical stacks.
In every vertical stack are some horizontal stacks.
All cards are default HA cards, except the custom Clock card, which I use for two years already and never caused any problem.
And, I already said, I’m not using HA OS, that was the topic starter his system.
I do run HA Supervised, all latest versions on fully up to date Debian Bullseye.
I don’t know, when it started, I’m not writing down exact notes about such things, I’m not running a police station, but a home.
Well, we are now two already with exactly the same problem, running different configs. That should point out in the direction, that there is something happening, not exactly our machine specific.
I didn’t assume anything, I was pointing out two scenario’s one if you did use Lay-out-card and one if you weren’t and asked you for more information so people can help.
No issues here with virtual-stack, good luck I hope someone can help you with only the info you provided 
For the record, everyone is using HA OS. Just because you’re running supervised, doesn’t mean you’re not running HA OS: Installation - Home Assistant.
I will gladly wait for help from someone without this “teachers attitude”.
Thanks for the time, you did spend on it, thanks for your lessons, sorry for not reacting exactly, as you expected, sorry for being me, dear master.
Maybe if you fix this kind of attitude, you will get help faster. It’s a normal response to ask for more information and code in order to know what we’re dealing with. Anyway, take care and I hope you have a better day tomorrow 
If I HAD the info, i had provide it. How hard is it to understand, that I can’t give you info, I don’t have?
I was working night shifts in a hospital the time it happened, had other things on my head, then writing down notes on HA it’s behavior. Sorry, that my priorities back then were saving lives.
Well, solving a problem is about collecting info we all DO HAVE, putting it together and trying to find a way.
Only accusing the one with a question of not handling as you wish is not an attempt to find this way walkable for all of us, it’s just criticism with no any direction to a result. I don’t need that kind of help.
Soon, there will be more people with this problem, and the solution will come thru another way. So i will just wait. Over one hour I will be saving lives again, way more important.
Cheers
I’ve changed the title to ’ recent update’ as I think we’ve agreed it’s not V8 realted.
This only happened in the past week, I did a ha update and an os update. Can’t figure out which versions but I was a couple behind about a month previous since I last did any updates - which is great btw it’s been so stable i forgot about HA)
and my back was only stored for 2 days and it’s gone now.
My homepage also is 3 vertical stacks, each with 3 or 4 horizontal stacks within.
I’m running fully kiosk browser on an android tablet.
What info would help diagnose this?
I’m tried on several different devices and browsers and it’s not occuring on others. Only on the tablet with fully kiosk.
Again seems to be ok on first load ,then a refresh the vertical stack position changes.
It’s like the webpage thinks the screen is narrower than it is and adjust the card layout for a narrow screen.
Hi, Have you tried in EDGE ?, Lately i’ve seen “unexplained” changes/behaviors in My Firefox
Actually A Browser is used in either cases, if im not wrong, so either a Browser of your choice, or your HOST/OS’s default browser
EDIT: Or the “Webview” builtin (If Android Companion)
I have been having the exact same issue. Fire Tablet 10s with Fully Kiosk Browser.
This is what its supposed to look like:
This is what it ends up looking like:
I do not see any problems…
