Confirmed

mlakuss 2014-08-20T14:34:44Z

Single player too

Berni U 2014-08-21T20:51:57Z

Not only while writing a sign, for me it happens every time I press the key.

galaxy_2alex 2014-08-22T15:35:40Z

Potentially a LWJGL issue.

Rebecca König 2014-08-24T19:06:23Z

Happens to me on a Ubuntu 14.04 and German keyboard layout as well.

It happens to me too. In Windows XP SP3, keyboard layout "International Spanish"

Rebecca König 2014-08-28T11:45:50Z

Still happening in pre-release 3.

Marvin 2014-08-29T20:47:57Z

Also happens by using German keyboard layout, not just with the spanish one.

Marcos Silva 2014-08-31T23:56:44Z

Also happens using Portuguese (portugal) keyboard layout

Rebecca König 2014-09-03T07:20:51Z

Confirmed for Minecraft 1.8.

violine1101 2014-09-05T21:50:27Z

It also happens outside of the Sign interface, but it doesn't happen if 'F2' isn't set as screenshot key.
(German keyboard layout, Windows 8.1, Minecraft 1.8)

Can someone update the description please?

EDIT: When changing to English (US) keyboard layout, MC doesn't take a screenshot when typing '<'. When changing to French (FR) or back to German (DE), it takes one.

2ND EDIT: Affected keyboard layouts are:
Belgian (BE), Catalan (ES), Croatian (HR), Danish (DA), Estonian (EE), Finnish (FI), French (FR), German (DE), Hungarian (HU), Icelandic (IS), Italian (IT), Luxembourgish (LU), Norwegian (NO), Portuguese (PT) and Spanish (ES)
And some more I didn't try, I guess.

3RD EDIT: It doesn't take a screenshot if 'Shift' or 'Control' ('AltGr' too) are pressed.

LazyMasterGamer 2014-09-20T14:34:12Z

Does the same with Belgian layout 🙂 (Win 8.1, MC1.8)
The "<" key is just next to my "Q" key which is the AZERTY equivalent of the "A" key on QWERTY, I'm taking 20 screenshot per day xD

Philippe Miguet 2014-10-07T21:29:28Z

I've got a British keyboard, set to German. Same issue.

marcono1234 2014-10-10T13:12:14Z

@Philippe Miguet:
But not when set to the default settings or?

Philippe Miguet 2014-10-10T13:16:59Z

Depends what you understand under default settings. The only thing I changed in Minecraft is the video settings (highest) and sound settings (mute music) and start chat with ENTER rather than T. However I did a setting reset... same issue. So technically... my MC setup is (almost) default. 🙂

Ah, and I forgot: I installed MC on my laptop when going on holiday, German keyboard, German setting... same issue with a virgin install.

Hun_Norberto 2014-10-15T19:15:52Z

It also affects Hungarian (HU) layout.

Rickard Åberg 2014-10-16T08:16:44Z

Same with Swedish QWERTY layout in Windows 8.1.

Very very annoying as I often by mistake press that key.

metarmask 2014-10-27T10:51:57Z

Maybe add all keyboards to the description/environment for easier access? @Alejandro Bentivengo

violine1101 2014-10-27T14:14:56Z

@metarmask - I already wrote all keyboard layouts I found out that they are affected into the comments. Read the older comments to see them.

It once happened to me in a laptop. Not in the desktop PC I usually use though.

Oskar Edholm 2014-12-21T14:03:22Z

Can confirm for Minecraft 1.8.2-pre1.

Confirm: laptop AZERTY keyboard, BE layout, 1.8+

Martin 2015-02-16T19:41:28Z

Happening to me on Windows 8.1. System language is English, keyboard layout is German. Very annoying. Workaround:

Binding the key to something else and saving the layout works. Unfortunately it just seems to be temporary as I'm taking screenshots again and it worked yesterday. You can rebind it again though.

violine1101 2015-02-16T21:53:53Z

Reminder to avoid further comment duplicates: I wrote some more details into the comments. Read the older comments to see them.

Martin 2015-02-17T20:33:47Z

My comment was not a duplicate as:

my system language is English and yours is probably German.
for me rebinding only works temporary and for you it seems to be a permanent workaround

In my opinion this makes it additional information and not a duplicated comment.

Another thing I just noticed is that it seems to be happening on greater than, not on less than. So Shift + < is taking screenshots for me. It does not matter if it is the left or the right Shift key though.

violine1101 2015-02-17T21:36:40Z

I didn't specificly name your comment as duplicate and it's not really constructive to discuss about comment duplicates.
Also, I don't think that the system language has something to do with the system language, it's definitely an inputting issue.
The workaround only works temporary, you say? Maybe you're switching versions sometimes because when you switch to a version below 1.7, some controls get resetted, including the control to take a screenshot.

However, the issue description is very insufficient and it would be great if a mod would update the description or at least add a disclaimer because this issue has many duplicates and it is - at least in my opinion - important to fix.

Also confirmed for Minecraft 1.8.3.

Erik Faxén 2015-03-16T22:04:00Z

I got this problem too on my keyboard with Swedish standard.
When writing < on a signpost or in the chat board my game takes a screenshot. It's really annoying.
However, when making a > sign (e.i. shift + <) does not make a screenshot for me. Only the < sign.
And this doesn't respond to the keyboard settings menu were it's still only set to take screenshot with standard F2.
I play version 1.8.3.

I hope this get fixet soon. < and > is kind of the most used letters on signpost in minecraft when making arrows. 🙂

Matti Ruohonen 2015-03-22T04:34:44Z

From my understanding, this bug occurs due to the following change in the client Minecraft class:

In 1.7.10 the keyboard input is read like so (using MCP names):
public void func_152348_aa()
{
int i = Keyboard.getEventKey();
...
}

Whereas in 1.8 it is read like:
public void dispatchKeypresses()
{
int i = Keyboard.getEventKey() == 0 ? Keyboard.getEventCharacter() : Keyboard.getEventKey();
...
}

This means that if the result from getEventKey() is 0, then the result from getEventCharacter() is used instead.
From a simple debug print (using a FI (= SWE?) keyboard/layout):

When pressing (and releasing) F2:
[06:12:57] [Client thread/INFO] [STDOUT]: eventCharacter: eventKey: 60 state: true
[06:12:57] [Client thread/INFO] [STDOUT]: eventCharacter: eventKey: 60 state: false

When pressing (and releasing) '<':
[06:13:19] [Client thread/INFO] [STDOUT]: eventCharacter: < eventKey: 0 state: true
[06:13:19] [Client thread/INFO] [STDOUT]: eventCharacter: eventKey: 0 state: false

So this means that when a user is pressing '<', the value of getEventKey() is zero, so the result of getEventCharacter() is used instead.
Now if you look at the ASCII table (for example at http://www.asciitable.com), you can see that the ASCII code for '<' is 60, which is the getEventKey() value for F2.
There may also be other collisions, where a "missing" getEventKey() value results in using the getEventCharacter() value of another key.

So the problem here is that the getEventKey() and getEventCharacter() values are not aligned, they should not be used in the same context like this.

Dobypeti 2015-04-14T18:58:59Z

Can confirm on a HU/Hungarian keyboard...

Reds Bone 2015-05-09T22:08:21Z

Confirmed on Slovenian keyboard. A screenshot is taken with < not only when typing it in chat and signs, but also when no GUI is open and even when the game is paused (ESC).

marcono1234 2015-05-20T13:34:24Z

@unknown's explanation makes sense, but I cannot confirm it for other keys (1.8.4)

Relates to:

MC-72856

Jonathan Gutiérrez 2015-06-01T23:54:29Z

Confirmed using Spanish-LatAm keyboard on 1.8.4.
Edit: Also happening in 1.8.6

MiningCreeper 2015-07-20T17:52:41Z

Confirmed using German keyboard on 1.8.7

Dobypeti 2015-07-28T21:05:09Z

Also confirmed on 1.8.7 using Hungarian (HU) keyboard.

Realised that only 'AltGr + í ' takes a screenshot.
(Pressing 'AltGr + M' does not takes a screenshot)

Wululululu 2015-07-29T15:39:09Z

Confirmed for 1.8.8 and 15w31a, German Keyboard on Windows 7
Edit: and 15w31b

Joel Puig Rubio 2015-07-29T22:36:48Z

They should try to fix this in tomorrow's snapshot, this bug is really annoying.

Pyry-Pekka Ronkainen 2015-07-31T06:11:37Z

Confirmed with Finnish layout/keyboard.

So annoying.

ZockerAxel 2015-08-01T11:13:44Z

Still in 15w31c on German Keyboard

Wululululu 2015-08-05T14:47:10Z

Another week, another version it's in.
This time 15w32a on Windows 10 though,
Edit2: and 15w32b
Edit3: and 15w32c
Edit1: I just checked again. 1.7.10 was the last full release that didn't contain this bug and 1.8 was the first that did.

ZockerAxel 2015-08-19T22:47:01Z

Fixed in 15w34a (at least on German Keyboards)

kumasasa 2015-08-20T05:19:48Z

@@unknown: No, this was fixed in 15w33c - see the top of this ticket.

Dobypeti 2015-08-20T13:58:17Z

Fixed on Hungarian keyboard, too. (Tested in 15w34a though)

Manel Almeida 2015-12-20T18:00:40Z

NOT resolved... 1.8.9 portuguese layout still taking screenshots...

violine1101 2015-12-20T18:05:56Z

It will be resolved in 1.9 (in fact, it is already in the 1.9 development versions). The only change in 1.8.9 was the Realms integration, so in 1.8.9 there were no bug fixes. There is no reason to reopen this issue since it is already fixed.

Martin Salthe 2016-02-07T19:27:41Z

Still getting error, I using a Nordic layout

Dlawso the Really Lucky Rabbit 2016-02-07T21:56:00Z

Martin, is this only on 1.8.9?

Tjo 2020-09-17T15:12:35Z

So basically:

To quick fix this, A: Use English keyboard setting.
To quick fix this, B: Switch the f2 button.

To fix it permanently in 1.8.9:

Find the faulty file

In your Minecraft folder, you will find the folder "versions"
Go to "1.8.9".
Open the "1.8.9.jar" with WinRAR (or whatever)
And extract the "ave.class"

Patch the faulty file

Download reJ: https://sourceforge.net/projects/rejava/
In reJ: Open the "ave" class you have extracted.
Find (ctrl+f): "public void Z()"

You will see this somewhere at the start of that text:

invokestatic int Keyboard.getEventKey()
ifne label_12
invokestatic char Keyboard.getEventCharacter()
goto label_15

Remove those 4 lines.
Save. Now you got a patched "ave.class" file.

Replace faulty with the patched file

Open the "1.8.9.jar" with WinRAR (or whatever)
Put the patched "ave.class" file into WinRAR to replace it.
Delete META-INF folder.
I use this json to accompany the jar: https://pastebin.com/GX7P95c1
DONE. Start Minecraft.
