Double key pressed with iBus (Linux)
lazarus / 1-Linux

If iBus is enabled, any key pressed will doubled in any edit box i.e.
TEdit  or TMaskEdit. 

for example if I press "SYS", the edit box will display "SSYYSS".
I have to turn off the iBus to prevent double key pressed.
iBus is very useful for input UTF8 Character ( Asia Character ). I
cannot turn-on and turn-off iBus very often.
It seems that only Lazarus's  application has problem with iBus.

Lazarus - 0.9.30.4,  gtk2
Ubuntu 11.10

Already well known bug.

Must find out howto recognize scim or ibus so then it won't be hard to
fix.

I've fixed that today. You can test trunk lazarus if it's ok.

This bug is still not fixed.  Tested in lazarus 1.4, amd64.

please check

by the way, if I run lazarus as root, then keyboard input would be
fine.  Run it as a regular user, I will get no input or sometimes
double input for a keystroke.

Hate to reply to an old topic, but this bug is still present when
trying to run Lazarus 1.6.0 on Ubuntu 16.04 LTS under VirtualBox.
Keystrokes display double.
