<![CDATA[Qt Creator 3.0.0 and Ctrl-Shift under X.Org X Server 1.15.0]]>I'm running Arch Linux with X.Org server 1.15.0 and I have Qt Creator 3.0.0 with Qt 5.2.0 installed from Arch repo.
I'm using Awesome window manager.
I'm using the following Xorg keyboard configuration:
@Section "InputClass"
Identifier "system-keyboard"
MatchIsKeyboard "on"
Option "XkbLayout" "us,ru"
Option "XkbVariant" ","
Option "XkbOptions" "grp:ctrl_shift_toggle,grp_led:scroll,compose:rwin"
EndSection
@
The problem is the following: whenever I use ctrl+shift to change keyboard layout, Qt creator loses the first key I press.
For example, if i keep pressing the same key (for example, "G") twice then switch layout, press it twice again, switch, press, etc., I get "пgпgпgпg" instead of "ппggппggппggппgg", because every key right afrer layout change is "eaten".

I've found the following: this happens if "grp:ctrl_shift_toggle" was set during Qt Creator startup. If it's started, and then I switch layout change to Alt+Shift:
@setxkbmap -option -option grp:alt_shift_toggle
@
then Qt Creator still "eats up" the first key after Ctrl+Shift released.
If Qt creator is started with "grp:with alt_shift_toggle" or with no toggle at all, everything is fine even if I switch to "grp:ctrl_shift_toggle" after it's start.

The problem doesn't seem to appear in Gnome DE, as long as it uses his own layout management routine, but I don't like new gnome, so I decided to stay in Awesome.
Any other app works fine.
Awesome doesn't use any "Ctrl+Shift+KEY" sequences. All his shortcuts involve a key with a logo between Ctrl and Alt.

I'm not sure if this is a bug of Qt creator or my own distro setup, so I've posted it here and not in the bugtracker.

Looks like it's not QtCreator-related bug, but it appears there.

Sounds you might be hitting a bug, did you already checked the "bug report system":http://bugreports.qt-project.org to see if it's something known ?

With version 3.1.2 my workaround doesn't work anymore. Qt creator keeps eating up the first symbol after Ctrl+Shift language switch. If I change grp:ctrl_shift_toggle to grp:alt_shift_toggle, Ctrl+Shift doesn't produce any bugs but doetn't switch layout as well.

Ctrl+Num/ doesn't seem to work, while Ctrl+'/' (where '/' is located on the left from Right Shift key) works.
This is independant of NumLock or current layout and sometimes is very frustrating.

EDIT: my current workaround is the following bash script:
@
#!/bin/bash
echo Starting Qt Creator with a keyboard workaround. What a shame :(
xkb_option=$(setxkbmap -query | grep options | sed 's/options:\s*//')

setxkbmap -option
qtcreator &
#another nasty workaround to make SURE creator has started before setxkbmap returns old layout
sleep 5
setxkbmap -option $xkb_option@

This is obviously an ugly solution :(

Is there anything else about Ctrl+Shift key combo in Creator?
