Keys getting stuck (in Minecraft)

[hawk]

Sorry if this is not the right place. I reported a bug for Minecraft about keys getting stuck and was referred to report it to LWJGL. The problem is that keys sometimes get "stuck" as if they are being pressed when they're not. This can have some pretty bad in-game consequences. It tends to happen when multiple keys are getting pressed at the same time or in short succession, but otherwise seems to be random (hard to reproduce consistently). I'm using OS X 10.6.8 and have Java 1.6.0_51-b11-457-10M4509.

Thanks!

Which version of LWJGL are you using? and which version of Minecraft?

It would also be helpful if you have a link to the bug on the Minecraft bug tracker, since sometimes further info/fixes can be found on there.

Also what type of keyboard do you have?

I have posted the full log output when launching Minecraft below.

LWJGL Version: 2.9.1

Minecraft 1.7.2 (this is the latest release)

The ticket I made is MC-39040 which was marked as duplicate of MC-886. The only advice given there, pretty much, is to update to the latest version of LWJGL, which was 2.8.4 or 2.8.5 or 2.9.0 nightly at the time. A lot of people reported that doing so didn't fix the issue for them but may have reduced the frequency of it happening. Myself I have 2.9.1 and obviously it's still happening for me.

I use the built-in QWERTY keyboard of my laptop with the Irish keyboard layout.

It looks like this but without the power button and slightly larger F-keys:
