@Brad: You do not need any mods to reproduce this bug. All you need to do is make a custom, superflat world.
@Zarquod: Oops, I assumed that the special builds I was referring to had Linux components as well. My apologies. I have no idea about Linux variants of the bug, I would suggest that you raise a bug on their GitHub issue tracker. That seems to be the only way to get their attention these days.
@Zarquod: The only link I've ever posted.
@Zarquod: If you follow the link in my comment, you will find premade binaries with the problem fixed. These do NOT come from their normal nightly build repo.
@GregFitzgerald. No, the v2.8.5 does not completely resolve the problem. You must use a nightly snapshot of v2.9.0.
LWJGL has already fixed the problem. You can install the newest version of it to fix the problem. We just need to convince Mojang to include the newest version with an update of Minecraft.
I have not been able to reproduce this, possibly because I don't have a good recipe to reproduce. I'm not convinced that it's actually fixed, but at the same time, I have no evidence that it still exists in a recent snapshot. It should probably be closed, but I don't understand how to change the status myself (if that's even possible).
I found out the window focus "bugs" are now "features". The nightly LWJGL load referenced in this issue report ( https://github.com/LWJGL/lwjgl/issues/1 ) seems to fix the problem for me.
I just checked their latest nightly snapshot but it has nasty window focus related bugs, so I can't confirm this bug has been fixed yet.
@zol: There are actually 3 different things going on here:
#1: The version of LWJGL that is shipped with Minecraft has a big problem with keys getting stuck, they get stuck down frequently.
#2: LWJGL v2.8.4 has a different key problem. Occasionally, they get stuck UP. I'll be walking around and clicking as I play, and sometimes (pretty rarely), I'll end up holding down a key, but Minecraft is SURE that I've already released it. This is probably 10x less often than the problems in the version that is shipped with Minecraft, and it's often less catastrophic to your game if your key is stuck up, so many people might not notice this.
#3: v2.8.5 has yet-another problem: clicking the mouse releases all keys. This completely breaks many operations like shift-clicking items, and trying to attack someone while running after them.
#4: v2.9.0 (at least the nightly version from two months ago) has yet-another problem: keys can sometimes (but rarely) get stuck either up or down. I've been told that the newest nightly should be better, and I'm going to try it soon myself to see if it's really resolved.
So, to conclude: sticky movement is the bug. Every known version of LWJGL has this problem, but to different extents. That is why some people think they've fixed the problem when upgrading their LWJGL.
I created a topic on their forums: http://lwjgl.org/forum/index.php/topic,4910.0.html
I agree with Zarquod. No version of LWJGL completely resolves this problem for me, a recent nightly snapshot is what I use, and it reduces the frequency of stuck keys, but it does not completely eliminate it.
Has anyone reported this problem to LWJGL? They have attempted to fix it. Do they even know they didn't completely fix it? It's been broken for many months. Maybe someone from Mojang will have to push the LWJGL guys to get it fixed, or go in and fix it themselves.
Argh, apparently file-dropper.com deleted the file. It is only supposed to delete it if it has not been downloaded in 30 days, and it's been less than that.
Anyway, so I don't have a backup of that world, and I already destroyed the blocks by right-clicking them.
I continue to experience this in 13w05b
Here's some testing I performed (I used the same world, same exact position) for all tests (fast graphics mode, normal distance):
Smooth lighting off:
13w04a: 68FPS
13w05a: 65FPS
13w05b: 68FPS
Smooth lighting on:
13w04a: 64FPS
13w05a: 39FPS
13w05b: 39FPS
I've attached a saved game that includes a spot where you can drown without any meter shown on the screen.
You don't even need the block above in all circumstances. Here's a shot of a setup that can drown you without a block above (and no meter visible). You must stand in the lowest block (the last block of flowing water).
Here's a copy of the Nether portion of my world. I only included the Nether portion to reduce the size of the download. Add this to any existing world, go to the Nether and go to the coordinates on the screenshot and you'll see the invisible blocks.
Marios: For each of those 3 versions, I completely deleted my .minecraft folder, allowed minecraft.exe to download a completely fresh copy, then I updated the LWJGL libraries.
I was able to reproduce my results. With 2.8.4 I still get keys stuck down; with 2.8.5, all keys are released when the mouse is clicked, and with 2.9.0, I can occasionally get keys stuck up.
I think you can only see the INSIDE of the object instead of the outside of the object.
