Invicible "Lava Source Blocks", These cannot be removed; placing blocks or using an empty bucket won't remove them. This seems pretty similar to
MC-12363, it might be related to a bucket desync but it doesn't work in the exact same way.Attatchment 1: (Cobbleston is placed)
Attachment 2: (Cobblestone Removed)
Attatchment 3: (Flowing Lava source block appears from where the lava was removed)
These lava blocks cannot be removed via bucket. After a few minutes of testing I concluded that the "Lava Source Block" might have turned invisible, using a bucket on a different block made the lava disappear.
Note: This is pretty similar to
bugs.mojang.com/browse/MC-12363but it highlights a different issue in the rendering engine rather than the internal server desyncing. It also is similar toMC-122957but the requirements for the bug to occur are not the same as the ones depicted in that bug report.









Update: This also happens through other semi-transparent blocks such as Honey Blocks and Slime Blocks, if you drop the item, it still does not render the particles through the item entity.
This might also be related to
MC-122914.Considering your hardware this might be a problem with your system.
Processor: AMD Ryzen 5 2600
RAM: 8GBx2 (HX424C15FB2/8)
This combination might not be able to process that many entities at a time. I suggest trying this on a different machine if possible to see if it happens again.
Will have to find another instance of this glitch, I will keep you update, thanks.
Successfully recreated the issue on a simulated environment, this time the F3 menu is enabled. The screenshots are attached to the original post.
