No - unfortunately this is still happening. Even after my client updated to 1.21.21. Skin/character changes to something different every time I open the game, just like shown in the video.
Don't know if this helps - but every time I first open the game and go to "Dressing Room", it gives me the "Character and Classic Skin Differences" pop-up, as if it's the first time I've ever been to the Dressing Room. I wonder if whatever is causing this problem is originating there.
Trying to update the skin through the Dressing Room still does not work (just like shown in the video) - but the current workaround of going to the Marketplace and resetting my skin that way every time I open the game is still working.
Was this a recent change? I can't find anything indicating that this is intended behavior. As I said I've been playing Minecraft on my Windows 10 PC for several years without signing in and have never experienced this issue until the recent update.
Even if that's now the case, it still doesn't explain why when I go through the Dressing Room and select the skin I want, the change doesn't go through and it still reverts back to a random character.
After reading through the older comments and the most recent one, I'm wondering if my issue isn't different from most of the other people's here. I tried the newly created world again and this time I just let it run for a bit, holding my laptop off the desk while it ran to improve airflow. After close to two minutes, CPU usage came back down and held at around 25% and RAM held more or less steady at just over 2 GB for the process. At that point, I was able to move around the world without significant changes to CPU or RAM. Later today I'll try some of my larger worlds - maybe there's something going on during initial world load that I just need to wait out? Just wish it didn't make my laptop sound like it was going to explode...
Not sure if I'm having the same issue, but I'm running the same Minecraft version on Windows 10. I'm seeing RAM just keep increasing and 100% CPU usage just standing in a newly created world and not moving around at all. I can't let mine run as long as your's because it sounds like my system is going to overheat. Oddly, I don't have any of these issues if I'm playing on a LAN game or on the Marketplace - it only happens when I load a local world.
I did not have a problem until 1.16. Running version 1.16.10. I have a Windows 10 laptop with an Intel i7-6700HQ 2.6 GHz and 32 GB of RAM. The vid card is a GeForce GTX 965M running the latest drivers. Everything is fine as long as I'm not in a world. Any world I load, even one I just created, as soon as the world launches, CPU and RAM start increasing immensely, even on a newly created world that is only 3.2 MB in size. CPU sits between 90-100% and RAM just keeps increasing (I watched it get up to 2 GB in less than a minute without even moving in the world - just standing there). I do not see much in the way of I/O or network activity. If I look at the threads with Process Explorer, I have seven threads of ucrtbase.dll each running at around 10-15% CPU each. It happens as soon as the world loads, and it stops as soon as I save and quit. I usually save and quit after about 15-30 seconds because the CPU and GPU fans in my laptop are running so hard I don't want my system to overheat. As you can see by my machine specs, while my machine is a few years old, it's still pretty powerful.
Also worth noting is that I can connect to worlds running on other devices in my house and my Minecraft client runs normally - between 5-10% CPU usage. So as long as the world isn't running locally on my Windows 10 system, Minecraft behaves normally. So whatever is causing the crazy CPU and memory usage is with local worlds only.
Hope this information is helpful to Mojang in figuring out a solution. My local worlds are pretty much unplayable. I'm going to keep looking at video settings and other workarounds in the meantime to see if I can get it usable again - I'll post back if I figure anything out.
Seeing exactly the same issue on 1.16.1. Friends tab shows that games are happening on the LAN but Xbox can't see them. Works fine the other way - someone hosting a game on an Xbox can be seen and joined by Android and Windows 10. I shouldn't have to pay for an Xbox Live subscription to play Minecraft on the LAN with the kids - has anyone from Mojang acknowledged this issue? Or is it a Microsoft issue?
This bug does not seem to be fixed. I am running snapshot 14w26c and the description of this bug consistently happens whenever a new portal is generated. Once the portal is generated, usually traveling through it works fine. Although a second unlit portal may sometimes be generated.
This is interesting - I just opened 1.21.30 for the first time on Windows 10, and while initially my character changed to Steve or someone else, eventually it did go back to my default "Smile" skin I had selected before closing the game.
I will keep testing with this version to make sure it wasn't just a fluke, but it's certainly promising.
I see alisistarsun said they're still having the issue on 1.21.30 on an iPad - so possible it's not fixed yet and I just got lucky. I'll post back after a couple of days to see if it's consistently remembering my skin.
UPDATE 9/19/24 - I've started the game several times since 1.21.30 dropped, and even though my character still briefly appears with one of the random skins as the game is first opening, it corrects to my usual skin within a second or two before I advance to the Play menu. I believe this issue has been fixed at least for Windows 10.
