ibus prevents minecraft to get keyboard input

[Ákos Maróy]

when ibus is running, some apps don't get keyboard input. for example, minecraft is one such application

when the ibus process is killed, minecraft gets keyboard input fine

I've tried this with three different JDKs, with the same result:

* OpenJDK 6
* OpenJDK 7
* Oracle JDK 7

I would expect minecraft to get keyboard input when ibus is running as well

Can you state your use case of minecraft more clearly?
Also, are you using any engine on IBus?

sure. if I have iBus running, and start the program called minecraft
(which is a java application, see here: http://www.minecraft.net/ ), the
minecraft doesn't get any of the keypresses pressed on the keyboard

if I kill the ibus process, the minecraft app will get they keypresses

I"m not sure what you mean - please clarify

Status changed to 'Confirmed' because the bug affects multiple users.

[Ma Hsiao-chun (mahsiaochun)]

I've successfully reproduced your issue; thank you for reporting.
I've also reported it to IBus upstream since this problem is beyond my knowledge of IBus.

[Ákos Maróy (akos-maroy)]

thank you!

Don't think this is an IBus bug as it works only when ibus isn't handling XIM, which is not possible for people using input method day to day. I believe this should be reported to Minecraft instead.

Aron, probably it is not, because it happens with Freemind too. When I talked with Takao Fujiwara, he suggested that the problem was JDK. He could not reproduce the issue on his systems.

I have tried all the differnt input software on a GTK2 desktop. I do not have any input problem with XIM, I do have input problemes everytime I use ibus in conjuction with a Java app, on this GTK2 deskop (LXDE).
