What? How is this considered multiple bugs? It’s all the same bug, it just has multiple affects.

I have the same issue. Use a keyboard and mouse with my huawei P30 pro and when i hover over a text field in the inventory for example the screen flashes or flickers. it only happens when moving the mouse from the item windows over the search bar, but not from outside the inventory UI to search bar or on top of UI over the search bar.

I managed to record a 30 hours timelapse of the server running 'idle', that's without any player joining and/or sending commands to the server. Every frame in this video is 1 second of real time, sped up 60 times, therefore allowing me not to loose a single recorded frame in the end product. What we can see here is a slow, but steady gain in memory usage; https://youtu.be/bnVBHPwExWc

Edit: It is worth mentioning that if the server sees any activity from a player, 3-4 hours is enough to max out the usage, thus requiring a hardware restart

Yes, it is quite similar.

I used to run the server on 12Gb memory, saw a huge spike in usage aftter jumping from 1.16.x to 1.18.x therefore turned it down to 10Gb, and even than the server would go over the specified amount. 

What is not included in the ticket you’ve mentioned is that the RAM ‘heap’ persists even after closing the server; only a total restart helps to remove it.

No, in that issue the hard drive is experiencing unforseen writes, in my case that/d be the memory getting bloated over the period the server is running

It's on the Playstation 4. The World is 90,0 MB big and the Error is in German called as "Ein Fehöer ist aifgetreten" and as "Es konnte Platz zum Hochladen deiner Welt gefunden werden. Bitte überprüfe deine Internet Verbindung." But my internet is working. The Export needs a few seconds, but at the Upload the Problem comes. 

i just wanted to play my old world with my kids from 1.14. my world are ALL corrupt. not a single one loads normally. they all look like yours! 

Alright OcelotOnesie. Thank you for letting me know.

DELETE MINECRAFT, THEN RE-INSTALL. This will solve this issue. 
Do not worry, all of your saved data will be saved. Just delete the app, then re-install. 

I made an account just to help everyone here. I was having this issue and found the fix on reddit, so i figured i'd share the solution with my fellow crafters. 
@Edward, you should be able to play now man. I hope so, anyway. Not being able to craft for a week is horrible. I hope this works for you. 

same

I guess logically you wouldn't consider water to be a potion..

These problems seem to always get flagged as technical support for some reason...

similar problem on my end

but yeah, you have a point

I would consider this a suggestion, not a bug.
