Android Studio: can't edit files after a while

Question

I just installed Android Studio and I have a problem:

after some time of work, I'm not able to edit files anymore, I have to restart the IDE to edit them for a while again.

That's very annoying. Is there a way to solve this? I saw others on google having almost the same problem (mostly on ubuntu), but I wasn't able to find any solution except a temporary one: if I click on the scrollbar of the file I'm able to edit it again, but the problem will be triggered again if I change file or do anything else outside of it; so the actual problem it's the editor not getting the focus by clicking on it.

I'm on Windows 8.1.

Assuming you are using Ubuntu OS.

As given here

The bug seems to be triggered by some missing synchronization between IBus (the server) and Xlib + AWT (the client JVM), exposed by a combination of a quick succession of key presses and the client’s slower event handling. The bug has already been reported upstream:

the bug is already reported here

The 2 workarounds that helped me were :

Workaround #1: Force ibus in synchronous mode

$ IBUS_ENABLE_SYNC_MODE=1 ibus-daemon -xrd

Do this preferably before starting Studio. This workaround was suggested in https://code.google.com/p/ibus/issues/detail?id=1733 for a different Java application facing the same problems.

Workaround #2: Disable IBus input in Studio

$ XMODIFIERS= ./bin/studio.sh

This will only disable input methods for Studio, not the other applications. Restarting the daemon while Studio is running (‘ibus-daemon -rd’) effectively disables the input methods for all other applications, and can also crash Studio's JVM with a segmentation fault.
