@Sakurai Yoshiyama
What are your system specs and have you updated your graphics drivers? I would advise to please lower the amount of comments at a time as well.
You are running CraftBukkit, which is not developed or supported by Mojang. File the bug with the CraftBukkit devs instead, as this is invalid here.
A workaround is to symlink libGLESv2.so.2 as libGLESv2.so and libEGL.so.1 as libEGL.so from your libraries (/usr/lib/x86_64-linux-gnu/) to a swiftshader folder in your minecraft launcher directory (/opt/minecraft-launcher/swiftshader). Seems some paths are a tad off.
Affects all 1.15 snapshots too. My theory is that some other sound is playing but it's incorrectly listed as a block being broken. I'm excluding typical overworld natural block broken sounds like a sheep eating grass, villagers replanting, leaves with vines decaying, etc as these are blocks being broken.
Related, the "Minecart Rolls" seems to show in subtitles very often too, but the sound effect has not played.
There is a reason why these releases are in snapshots and not an actual release. We, the players, help bug test and experiment with changes leading up to the release to help benefit Mojang and their development. If you want a more stable and actually release worthy version, 1.14.4 is the latest.
Looks like it isn't rendering based on look direction like it should. If you are at the south of the portal (portal is north of you) and look around without moving, the portal stays still in your view.
If you could not waste space and fill out a proper bug report or look for ones already posted, that would be great. These aren't mistakes, it's part of the typical development process. Snapshots are developmental versions and it is expected to have bugs and issues. It's a reason why snapshots are available to the public, so we can test and report bugs and Mojang can get it right.
The title contains your problem. This is not a bug, this is either a lack of updates drivers, or the lack of OpenGL support for your hardware. Nothing really specific to Minecraft.
I've noticed this a lot. Recently had to reinstall an OS due to improper graphics configurations and I chose KDE Plasma. Instantly, I realized this happening, especially where I move a lot on creative. It's especially annoying in survival because I have nearly died a lot due to this. I can't run fullscreen as I like to quickly be able to look something up or check something.
Marcono1234,
I have finally been able to force a crash. I have put the crash report in a pastebin and linked it in the description. I hope this helps.
Marcono1234,
No, naturalRegeneration is set to true, and even setting it to false and back continues to give an odd effect to the hunger and health regeneration.
Test it my friend, what you will see will be amazing...
DE-Mod yourself!
See screen shots!
NO TEXTURES HAVE BEEN CHANGED! ONLY THE FACT THAT IT BECOME DARKER! Sometimes lighter(in lighting not weight)
It is posible they can affect ladder's! It's possible!
Not just dark but light colors too! I see no texture changes!
Facepalm
Then don't use firefox! Complainer
NO PROOF!! Failure! Fake!
Still a problem inĀ 2.1.12464. Minecraft is still looking for libraries in a folder called swiftshader in it's working directory despite it not existing. The difference now is that the launcher no longer blanks out but informs you of your device not supporting WebGL, despite this not being the case. My previous workaround of copying/symlinking libGLESv2 and libEGL to a folder called 'swiftshader' in '/opt/minecraft-launcher' still works.
