Here to report the same, as redundant as it is. Had the cape equipped, though at the time didn't think as to why the cape wasn't listed until after I had switched to the Pancape.
Forgot about the fact that screenshots are pretty useful, though this has occurred in the official 1.16 release in my experience.
Pitching in a bit of my experience - seems to only use languages that my browser (Chrome) has installed. I'm in the US and English is set as the default, though the website would load French since I have that language installed. Removing French just caused it to load another one of my installed languages other than the default.
This has been fixed and should probably be marked off as resolved.
Also in 1.14.2, and 1.14.3 Pre-release 2.
Still says it's using OpenGL 4.3..?
Edit: Woops, realized I was using the 32-bit Java exec. Upon using the 64-bit Java exec I get the same results as simply using what Minecraft includes. Solved?
For clarification, does this explain why it decides to magically work when I use the executable in the Java folder?
This is still an issue. I've also tried for 1.13.1 and I get the same outcomes. Something I failed to mention is that even reinstalling the Windows OS does not solve it.
This appears intended and is not restricted to multiplayer. Hold shift to go down faster, if this is what you are referring to.
The issue persists. I am unable to use the new launcher to connect with older Minecraft versions.
1.17.1
